摘要:

为分析采用等增益合并的协作自动重传请求(CARQ)网络在Nakagamim信道中的性能,利用一种新的近似方案推导出其在高信噪比时的误帧率表达式,其结果适用于任意中继数的情况. 仿真结果表明,与传统的自动请求重传(ARQ)网络相比,CARQ可以获得更好的性能.

关键词: 协作自动重传请求, 等增益合并, 中继

Abstract:

To analyze the performance of cooperative automatic repeat request (CARQ) network, which adopts equal gain combining over Nakagamim channels, an approximation strategy is utilized to derive frame error probability at high signaltonoise ratio. It is applied for the networks with arbitrary relay number. Simulations verify the reliability of the theoretical analysis and the superiority of CARQ when compared with traditional automatic repeat request (ARQ). 

Key words: cooperative automatic repeat request, equal gain combining, relay
