We study the performance of cognitive radio networks with imperfect spectrum sensing and backup channels (BCs). The cognitive radio network is an opportunistic spectrum access (OSA) network which consists of a primary system serving primary users (PUs) and a secondary system serving secondary users (SUs). There are N primary channels (PCs) licensed to PUs and M BCs dedicated to SUs. The PUs have strict priority over the SUs in utilizing PCs and the SUs first try to opportunistically access the… CONTINUE READING
