Topics In Modeling, Analysis And Optimisation Of Wireless Networks
(2010-11-02)
The work in this thesis is concerned with two complementary aspects of wireless networks research; performance analysis and resource optimization. The first part of the thesis focusses on the performance analysis of IEEE ...
Rate-Distortion Performance And Complexity Optimized Structured Vector Quantization
(2011-02-09)
Although vector quantization (VQ) is an established topic in communication, its practical utility has been limited due to (i) prohibitive complexity for higher quality and bit-rate, (ii) structured VQ methods which are not ...
Distributed Joint Source-Channel Coding For Multiple Access Channels
(2010-12-31)
We consider the transmission of correlated sources over a multiple access channel(MAC). Multiple access channels are important building blocks in many practical communication systems, e.g., local area networks(LAN), cellular ...
Performance Analysis Of Multiuser/Cooperative OFDM Systems With Carrier Frequency And Timing Offsets
(2011-02-03)
Multiuser and cooperative orthogonal frequency division multiplexing(OFDM) systems are being actively researched and adopted in wireless standards, owing to their advantages of robustness to multipath fading, modularity, ...
Coplanar Capacitive Coupled Probe Fed Ultra-Wideband Microstrip Antennas
(2010-12-07)
Modern wireless communication systems call for ultra wideband operations to meet the continuous growth in the number of users of these systems. Since antenna is an integral part of any wireless communication system ...
Belief Propagation Based Signal Detection In Large-MIMO And UWB Systems
(2011-02-03)
Large-dimensional communication systems are likely to play an important role in modern wireless communications, where dimensions can be in space, time, frequency and their combinations. Large dimensions can bring several ...
Analytical And Numerical Study Of Propagation In Optical Waveguides And Devices In Linear And Nonlinear Domains
(2010-07-23)
The objective of this thesis is to study of optical effects, arising in the form of non-uniform waveguide structure, complicated refractive index profiles or due to pulse propagation in dense wavelength division multiplexing ...
Low Decoding Complexity Space-Time Block Codes For Point To Point MIMO Systems And Relay Networks
(2010-07-12)
It is well known that communication using multiple antennas provides high data rate and reliability. Coding across space and time is necessary to fully exploit the gains offered by multiple input multiple output (MIMO) ...
QoS Aware Quorumcasting Over Optical Burst Switched Networks
(2010-10-11)
Recently there is an emergence of many Internet applications such as multimedia, video conferencing, distributed interactive simulations (DIS), and high-performance scientific computations like Grid computing. These ...
Diversity-Multiplexing Gain Tradeoff Of Cooperative Multi-hop Networks
(2010-08-23)
We consider single-source single-sink (ss-ss) multi-hop relay networks, with slow-fading links and single-antenna half-duplex relay nodes. While two-hop cooperative relay networks have been studied in great detail in terms ...
