Spectrum Sensing in Cognitive Radios using Distributed Sequential Detection
(2018-03-17)
Cognitive Radios are emerging communication systems which efficiently utilize the unused licensed radio spectrum called spectral holes. They run Spectrum sensing algorithms to identify these spectral holes. These holes ...
Finding A Subset Of Non-defective Items From A Large Population : Fundamental Limits And Efficient Algorithms
(2017-07-12)
Consider a large population containing a small number of defective items. A commonly
encountered goal is to identify the defective items, for example, to isolate them. In the classical non-adaptive group testing (NAGT) ...
Optimal Amplify-And-Forward Relaying For Cooperative Communications And Underlay Cognitive Radio
(2017-08-21)
Relay-assisted cooperative communication exploits spatial diversity to combat wireless fading, and is an appealing technology for next generation wireless systems. Several relay cooperation protocols have been proposed in ...
Role of Channel State Information in Adaptation in Current and Next Generation Wireless Systems
(2017-11-24)
Motivated by the increasing demand for higher data rates, coverage, and spectral efficiency, current and next generation wireless systems adapt transmission parameters and even who is being transmitted to, based on the ...
Interference Modeling in Wireless Networks
(2017-10-26)
Cognitive radio (CR) networks and heterogeneous cellular networks are promising approaches to satisfy the demand for higher data rates and better connectivity. A CR network increases the utilization of the radio spectrum ...
