A joint receive diversity and power control (JRDPC) algorithm is proposed for cognitive radio networks. By this algorithm, the quality of service for the primary user can be ensured and the secondary user (SU) can make its signal-to-interference-plus-noise ratio (SINR) converge to the SINR requirement. To realize rate adaptation, we propose the rate adaptation algorithm that works with the proposed JRDPC algorithm. We assume that there is a throughput requirement (which is determined by the transmission rate and the SINR), and the proposed rate adaptation algorithm aims to adapt SUs transmission rate to the SINR so that SUs adapted transmission rate can meet the throughput requirement. Simulation results show that compared to rate adaptation without joint receive diversity and power control, the proposed rate adaptation algorithm increases SUs probability of feasibility (for making SUs adapted transmission rate meet the throughput requirement).
