Performance Analysis of Underlay Cognitive Radio Systems: Estimation-Throughput Tradeoff
Ankit Kaushik, Shree Krishna Sharma, Symeon Chatzinotas +2
In this letter, we study the performance of cognitive Underlay Systems (USs) that employ power control mechanism at the Secondary Transmitter (ST). Existing baseline models conside…
Impact of Transceiver Impairments on the Capacity of Dual-Hop Relay Massive MIMO Systems
Anastasios K. Papazafeiropoulos, Shree Krishna Sharma, Symeon Chatzinotas
Despite the deleterious effect of hardware impairments on communication systems, most prior works have not investigated their impact on widely used relay systems. Most importantly,…
Sensing-Throughput Tradeoff for Interweave Cognitive Radio System: A Deployment-Centric Viewpoint
Ankit Kaushik, Shree Krishna Sharma, Symeon Chatzinotas +2
Secondary access to the licensed spectrum is viable only if interference is avoided at the primary system. In this regard, different paradigms have been conceptualized in the exist…
Coordinated Multibeam Satellite Co-location: The Dual Satellite Paradigm
Dimitrios Christopoulos, Shree Krishna Sharma, Symeon Chatzinotas +1
In the present article, a new system architecture for the next generation of satellite communication (SatComs) is presented. The key concept lies in the collaboration between multi…
Estimation-Throughput Tradeoff for Underlay Cognitive Radio Systems
Ankit Kaushik, Shree Krishna Sharma, Symeon Chatzinotas +2
Understanding the performance of cognitive radio systems is of great interest. To perform dynamic spectrum access, different paradigms are conceptualized in the literature. Of thes…
