Algorithms For Spatial Modulation Systems
(2018-07-28)It is well known that multiple antennas at the transmitter and receiver are imperative for reliable and high data-rate communication over wireless channels. However, these systems essentially need multiple radio frequency ... -
Analysis and Optimization of Cooperative Amplify-and-Forward Relaying with Imperfect Channel Estimates
(2018-03-17)Relay-based cooperation promises significant gains in a wireless network as it provides an inde-pendent path between a source and a destination. Using simple single antenna nodes, it exploits the spatial diversity provided ... -
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 ... -
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 ... -
Coding For Multi-Antenna Wireless Systems And Wireless Relay Networks
(2009-03-04)Communication over a wireless channel is a challenging task because of the inherent fading effects. Any wireless communication system employs some form of diversity improving techniques in order to improve the reliability ... -
Coding For Wireless Relay Networks And Mutiple Access Channels

Cooperative Communication In Store And Forward Wireless Networks Using Rateless Codes
(2013-08-30)In this thesis, we consider a cooperative relay-assisted communication system that uses rateless codes. When multiple relays are present, the relay with the highest channel gain to the source is the first to successfully ... -
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 ... -
Delay Differentiation By Balancing Weighted Queue Lengths
(2017-05-04)Scheduling policies adopted for statistical multiplexing should provide delay differentiation between different traffic classes, where each class represents an aggregate traffic of individual applications having same ... -
Delay Minimization of an M/M/1 Point-to-Point Link Model Subject to Throughput and Power Constraints
(2018-02-15)In this thesis, we address the problem of minimizing the average delay of data pack-ets served by a transmitter on a static, point-to-point link. The transmitter dynamically chooses state-dependent admission and transmission ... -
Design And Analysis Of Microstrip Ring Antennas For Multi-frequency Operations
(2013-06-18)In this research we attempted several modifications to microstrip ring/loop antennas to design multi-frequency antennas through systematic approaches. Such multi-frequency antennas can be useful while building compact ... -
