Cooperative Relaying in Underlay Cognitive Systems with Hardware Impairments
Nikolaos I. Miridakis, Dimitrios D. Vergados, Angelos Michalas
The performance of an underlay cognitive (secondary) dual-hop relaying system with multiple antennas and hardware impairments at each transceiver is investigated. In particular, th…
On the Ergodic Capacity of Underlay Cognitive Dual-Hop AF Relayed Systems under Non-Identical Generalized-K Fading Channels
Nikolaos I. Miridakis
The ergodic capacity of underlay cognitive (secondary) dual-hop relaying systems is analytically investigated. Specifically, the amplify-and-forward transmission protocol is consid…
Green Cognitive Relaying: Opportunistically Switching Between Data Transmission and Energy Harvesting
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, George C. Alexandropoulos +1
Energy efficiency has become an encouragement, and more than this, a requisite for the design of next-generation wireless communications standards. In current work, a dual-hop cogn…
