提出了考虑多个干扰的解码转发主动机会中继选择协议.针对存在直通链路的中继模型,在多个干扰对中继节点和目的节点同时产生影响的情况及独立不同分布的瑞利信道环境下,推导出了目的节点采用最大比合并时的中断概率,并对结果进行了仿真验证.在存在多个干扰的情形下,考虑干扰的中继选择方案优于经典的中继选择方案,中继选择协议可以减少干扰对系统的影响.
This paper proposes a decoding-forward active opportunistic relay selection protocol that considers multiple interferences.Aiming at the existence of a direct-link relay model, when multiple interferences affect both the relay node and the destination node at the same time and different independent Rayleigh channels Environment, the probability of outage when the destination node adopts the maximal ratio combination is deduced, and the result is verified by simulation.Under the condition of multiple interferences, the relay selection scheme considering interference is superior to the classical relay selection scheme, Relay selection protocol can reduce the impact of interference on the system.
