摘要：
A traffic-rate-based joint power control strategy for co-channel operation in cognitive radio system is proposed. The strategy allocates transmitting power according to both terminals' locations and traffic data rate requirements, so heterogeneous terminals can be provided with desired transmitting power. System simulation shows that the proposed strategy can achieve higher system throughput and spectrum utilization than two existing uniform power allocation schemes.
