多中继去噪重传物理层网络编码自适应分集策略
Denoise-and-forward based adaptive diversity scheme for physical-layer network coding with multiple relay node
摘要
Abstract
The capacity issue of a denoise-and-forward(DNF) protocol was focused on based PNC system of frequency non-selective Rayleigh fading channel. First, the total sum-rate of the system was derived. With the derived sum-rate expression, two policies maximizing the system sum-rate are proposed. On this basis, a novel adaptive diversity scheme was proposed. Closed-form expressions of the system outage probability with the new proposed scheme as well as the amplify-and-forward (AF) based PNC system and the conventional direct transmission were derived over frequency-nonselective Rayleigh fading channels. Simulation experiments are conducted and the results show that the outage performance of the system can be im-proved significantly compared to the AF based PNC system and the conventional direct transmission scheme.关键词
