摘要: 基于多波模信道模型建立了矩形隧道多中继协作通信系统模型，给出了放大转发和译码转发协作模式下多中继协作通信系统的信道容量计算公式。在系统总功率受限的情况下，提出了基于遗传算法的隧道多中继放大转发协作通信系统优化功率分配方法和隧道多中继译码转发协作通信系统多重KKT优化功率分配方法，以优化系统的信道容量。仿真结果表明，隧道多中继协作通信系统优化功率分配方法可提升系统的信道容量。Abstract: The multi-relay cooperative communication system model in rectangular tunnel based on multimode channel model was established, and the channel capacity calculation formulas of multi-relay cooperative communication system in amplify and forward mode and decode and forward mode were given. Under the circumstance of limited power in tunnel, optimal power allocation method of amplify and forward multi-relay cooperative communication system based on genetic algorithm and multiple KKT optimal power allocation method of multi-relay cooperative communication system in decode and forward were proposed to optimize the channel capacity. Simulation results show that the proposed optimal power allocation methods can improve channel capacity of the tunnel multi-relay cooperative communication system.
