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 ...
Generalized Analytic Signal Construction and Modulation Analysis
(2018-04-02)
This thesis deals with generalizations of the analytic signal (AS) construction proposed by Gabor. Functional extensions of the fractional Hilbert Transform (FrHT) are proposed using which families of analytic signals are ...
Perceptual Criterion Based Rate Control And Fast Mode Search For Spatial Intra Prediction In Video Coding
(2010-03-11)
This thesis dwells on two important problems in the field of video coding; namely rate control and spatial domain intra prediction. While the former is applicable generally to most video compression standards, the latter ...
