Robust Precoder And Transceiver Optimization In Multiuser Multi-Antenna Systems
(2013-10-04)
The research reported in this thesis is concerned with robust precoder and transceiver optimization in multiuser multi-antenna wireless communication systems in the presence of imperfect channel state information(CSI). ...
Fusion of Sparse Reconstruction Algorithms in Compressed Sensing
(2018-06-08)
Compressed Sensing (CS) is a new paradigm in signal processing which exploits the sparse or compressible nature of the signal to significantly reduce the number of measurements, without compromising on the signal reconstruction ...
Low-PAPR, Low-delay, High-Rate Space-Time Block Codes From Orthogonal Designs
(2011-02-03)
It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. Some of the design criteria of the space-time block codes ...
Spectral And Temporal Zero-Crossings-Based Signal Analysis
(2017-09-20)
We consider real zero-crossing analysis of the real/imaginary parts of the spectrum, namely, spectral zero-crossings (SZCs). The two major contributions are to show that: (i) SZCs provide enable temporal localization of ...
Analysis of Local Field Potential and Gamma Rhythm Using Matching Pursuit Algorithm
(2017-11-17)
Signals recorded from the brain often show rhythmic patterns at different frequencies, which are tightly coupled to the external stimuli as well as the internal state of the subject. These signals also have transient ...
