摘要 为了降低two-path中继系统的通信中断概率,针对DF协议中继,推导了two-path中继系统在存在中继间干扰情况下的中断概率闭式解,并在总功率受限的情况下,提出了一种最小化中断概率的最优功率分配算法。仿真验证结果表明该算法能够有效地降低系统的中断概率,提高系统的性能。 In order to decrease the outage probability of two-path relay system,this paper derived a closed-form solution of outage probability in DF two-path relay system with the inter-relay interference,and then proposed an optimal power allocation algorithm to minimize the outage probability under the limited total power.The simulation results show that this algorithm can effectively decrease the outage probability and improve the performance of the system.
