Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error
Shaker, Reza; Khakzad, Hamidreza; Taherpour, Abbas; Khattab, Tamer; Hasna, Mazen Omar ( IEEE , 2014 , Conference Paper)In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...
