We consider a cognitive radio system with M primary channels where users' data transmissions follow a slotted structure. We consider the scenario where the channel availability statistics are correlated across channels as well as across time slots. In each slot, the cognitive user (CU) senses channels one by one until a suitable channel is found for data transmission. CU adapts theCognitive Radio data rate based on the channel's fading gain. We employ a Markov chain model to capture the channel… CONTINUE READING
