Topics In Performance Modeling Of IEEE 802.11 Wireless Local Area Networks
(2011-07-11)
This thesis is concerned with analytical modeling of Wireless Local Area Networks (WLANs) that are based on IEEE 802.11 Distributed Coordination Function (DCF). Such networks are popularly known as WiFi networks. We have ...
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 ...
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 ...
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 ...
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 ...
Diversity-Mutiplexing Tradeoff Of Asynchronous Cooperative Relay Networks And Diversity Embedded Coding Schemes
(2010-08-23)
This thesis consists of two parts addressing two different problems in fading channels.
The first part deals with asynchronous cooperative relay communication. The assumption of nodes in a cooperative communication relay ...
Demodulation of Narrowband Speech Spectrograms
(2017-11-22)
Speech is a non-stationary signal and contains modulations in both spectral and temporal domains. Based on the type of modulations studied, most speech processing algorithms can be classified into short-time analysis ...
Harmonic Sound Source Separation in Monaural Music Signals
(2017-11-27)
Sound Source Separation refers to separating sound signals according to their sources from a given observed sound. It is efficient to code and very easy to analyze and manipulate sounds from individual sources separately ...
