基于位置和干扰限制的认知中继选择算法
Cognitive Relay Selection Algorithm Based on Location and Interference Constraint
摘要
Abstract
Aiming at the problems of low transmission rate and the interference introduced to the primary user by cognitive users, this paper proposes a cognitive relay selection algorithm based on location and interference constraint, the relay is chosen according to the relation between the location of cognitive relay nodes and the transmission rate of the relay link, and the optimal transmitting power is determined under the interference restraint of cognitive users to primary users. Simulation results show that the algorithm can both increase the throughput and restrict the interference of cognitive users to primary users successfully.关键词
