Wireless communication networks are enabling an ever increasing set of applications. This set spans domain areas such as traditional telephony, ubiquitous access to information and computation, cyber-physical infrastructure monitoring, and disaster recovery. The service quality and scalability of these applications is. Recently there has been a growing interest in using infrared light for broadband indoor wireless communications. There are two major limitations for establishing a wideband infrared communications link. The first and most important limit is the power requirements of such a link. The second important impairment is the intersymbol interference caused by multipath dispersion. In this paper we address the issue of designing an optimized transmission system to provide the best power efficiency for an infrared link. Important parameters that should be considered for this design and some examples of efficient link designs are discussed. The suggested designs can improve the power efficiency of an indoor infrared link up to 4 to 8 d Bo while providing a smaller rms delay spread, more robustness to shadowing and a more uniform distribution of power. Characteristics of the indoor infrared channel depends upon the directions of the receiver.

Information Technology - It defines an industry that uses computers, networking, software programming, and other equipment and processes to store, process, retrieve. Concerns still exist over the safety of prolonged exposure to radio frequency (RF) wireless transmissions and there are also potential data security issues due to remote signal interception. Airborne ultrasound may be used as an alternative to RF for indoor wireless communication systems for securely transmitting data over parallel channels at short ranges. This thesis describes the design and evaluation of an airborne ultrasonic communication system using capacitive transducers. In this study, basic digital modulation schemes, such as ON-OFF keying (OOK) and binary phase-shift keying (BPSK), were implemented successfully over multiple parallel channels for data transmission over an air gap of up to 10 m with wireless synchronization using ultrasonic means. A simulation model that can precisely predict ultrasonic signals through the air channel was also created to help with signal characterisation. To further improve the bandwidth efficiency and eliminate the need for filtering, quadrature amplitude modulation (QAM) using orthogonal frequency division multiplexing (OFDM) method was investigated. The recorded data rate was 800 kb/s at 0.7 m with no measurable errors using prototype broadband ultrasonic transducers, and 180 kb/s at 6 m using relatively narrowband commercially available transducers. This thesis has also looked at implementing an indoor communication network with ceiling-mounted base stations and a mobile communicator for practical applications.
A Statistical-Physics Approach to the Analysis of Wireless Communication Systems. MAKSYM GIRNYK. Doctoral Thesis in Telecommunications. Stockholm, Sweden 2014. Wireless Communication is soon going to replace the traditional wired mode of communication. With the advent of wireless technology, communication has become more convenient and effective. Now there is no need to install lengthy wires to set up the network. Wireless technology uses radio waves for communication rather than relying on wires. There are various topics in wireless communication for thesis, project and research. Following are the list of current thesis topics in wireless communication: MIMO is an antenna-based technology of wireless communication in which both sender and receiver uses multiple antennas to enhance the capacity of a radio link.
Massive Access for Machine-to-Machine Communication in Cellular Networks Massive Machine-to-Machine Communication in Long Term Evolution and Long Range Wide Area Network. René Brandborg Sørensen. Wireless Communication Systems, Master, Master Programme 4. term, 2016. Student thesis Master thesis. Abstract This study investigates the use of error control code, discrete wavelet transform (DWT) and artificial neural network (ANN) to improve the link performance of an indoor optical wireless communication in a physical channel. The key constraints that barricade the realization of unlimited bandwidth in optical wavelengths are the eye-safety issue, the ambient light interference and the multipath induced intersymbol interference (ISI). Eye-safety limits the maximum average transmitted optical power. The rational solution is to use power efficient modulation techniques. Further reduction in transmitted power can be achieved using error control coding. A mathematical analysis of retransmission scheme is investigated for variable length modulation techniques and verified using computer simulations. Though the retransmission scheme is simple to implement, the shortfall in terms of reduced throughput will limit higher code gain. Due to practical limitation, the block code cannot be applied to the variable length modulation techniques and hence the convolutional code is the only possible option.

PhD thesis, University of Glasgow. Full text available as. Wang, Zichen, Doppler spread estimation in high mobility wireless communications, Master of Engineering - Research thesis, School of Electrical, Computer and Telecommunications Engineering, University of Wollongong, 2015. Wireless communication systems have experienced phenomenal growth over the last three decades. Tremendous research efforts have been devoted, andmany important developments have been made. Future wireless communication systems aim at providing reliable data transmission even under high mobility scenarios. One of the challenging issues is the large Doppler spread, which is caused by the high mobility of a wireless terminal and may lead to severe communication performance loss. Doppler spread is a measure of spectral broadening of the rate of change in a mobile fading channel which is proportional to the mobile speed. As Doppler spread is a significant parameter of themobile channel, it is important to a number ofwirelessmobile applicationswhich require the knowledge of the fading rate of channel variations or the mobile speed. Therefore, the large Doppler spread in high mobility wireless communication systems cannot be negligible anymore and an accurate estimate of Doppler spread is imperative to develop future mobile communication systems for high speed vehicles.

Low-maintenance requires years of lifetime, that can only be achieved with unprecedented energy efficiency of communication protocols. Specifically, we focus on the MAC and. This thesis reports the methods, the deployment strategies and the resulting system performance improvement of in-building environmental modification. With the increasing use of mobile computing devices such as PDAs, laptops, and the expansion of wireless local area networks (WLANs), there is growing interest in increasing productivity and efficiency through enhancing received signal power. This thesis proposes the deployment of waveguides consisting of frequency selective surfaces (FSSs) in indoor wireless environments and investigates their effect on radio wave propagation. The received power of the obstructed (OBS) path is attenuated significantly as compared with that of the line of sight (LOS) path, thereby requiring an additional link budget margin as well as increased battery power drain. In this thesis, the use of an innovative model is also presented to selectively enhance radio propagation in indoor areas under OBS conditions by reflecting the channel radio signals into areas of interest in order to avoid significant propagation loss. An FSS is a surface which exhibits reflection and/or transmission properties as a function of frequency. An FSS with a pass band frequency response was applied to an ordinary or modified wall as a wallpaper to transform the wall into a frequency selective (FS) wall (FS-WALL) or frequency selective modified wall (FS-MWALL). Measurements have shown that the innovative model prototype can enhance 2.4GHz (IEEE 802.11b/g/n) transmissions in addition to the unmodified wall, whereas other radio services, such as cellular telephony at 1.8GHz, have other routes to penetrate or escape.

Park, Jeoong Sung, "Low Power Wireless Video Communication System For Mobile Devices" 2017. Engineering Ph. D. The term wireless refers to the communication or transmission of information over a distance without requiring wires, cables or any other electrical conductors. Wireless communication is one of the important mediums of transmission of data or information to other devices. The Communication is set and the information is transmitted through the air, without requiring any cables, by using electromagnetic waves like radio frequencies, infrared, satellite, etc., in a wireless communication technology network. At the end of the 19th century, the first wireless communication systems were introduced and the technology has significantly been developed over the intervening and subsequent years. Today, the term wireless refers to a variety of devices and technologies ranging from smart phones to laptops, tabs, computers, printers, Bluetooth, etc. In recent days, the wireless communication technology has become an integral part of several types of communication devices as it allows users to communicate even from remote areas. The devices used for wireless communication are cordless telephones, mobiles, GPS units, Zig Bee technology, wireless computer parts, and satellite television, etc. Satellite Satellite communication is one of the wireless technologies, which is widely spread all over the world allowing users to stay connected virtually anywhere on the Earth.
Abstract—Traditional approaches using superimposed signals in wireless sensor networks have high demands on the hardware capabilities of a single network node. This work loosens these constraints and derives a communication system for low-resource wireless sensor networks requiring no complex signal processing. ST’s portfolio of interfaces includes standard interfaces (such as RS-232, RS-422, RS-423, RS-485, LVDS, and USB), I/O expanders, level translators and application-specific interfaces for smart cards and Ethernet.
I declare that the work, ideas & codes in the following thesis are mine unless they are quoted. I declare that the Wireless communication package is chosen, bought and implemented by me. I designed and implemented the software for the Ute's computer that reads the Hyperkernel memory, receive messages and send. This work presents a study of low-cost antennas and communication systems to support the burgeoning demand for bandwidth in the next generation wireless communications and networks (5G) and/or Internet of Things (Io T). The work was divided into three different fields all aimed at low-cost solutions of enabling next generation networks (5G) and Io T. The first part of the study involves study of low-cost fabrication of antennas and radio frequency (RF) guided wave structures up to 10 GHz using the thermal transfer printing (TTP) technique on renewable, light weight, flexible and low-cost substrates. The thermal transfer printing method for electronics was characterised from DC to 10 GHz and benchmarked for performance against inkjet printing technique which is an established technique for printed electronics. TTP achieved similar or better read range to inkjet printed radio frequency identification (RFID) antennas that were used in this study.
