摘要

本文提出了用于应急响应通信的编码无线自组网的性能评价。由于传输范围有限，在源和目的之间可能存在许多中间中继节点，这些中继节点使用混合放大转发(AF)/解码转发(DF)协议来传输源传输。所有节点都包含单天线，考虑基于OFDM的低密度奇偶校验(LDPC)编码传输。推导了该系统的闭式误码率表达式。性能评估表明，LDPC编码自组网的误码率优于非编码自组网。

Performance analysis of LDPC coded wireless ad-hoc network for emergency response communications

In this paper, we present the performance evaluation of coded wireless ad-hoc network for emergency response communication. Due to the limited transmission range, a number of intermediate relaying nodes may exist between source and destination and these convey source transmission using hybrid Amplify-and-forward (AF)/Decode-and-forward (DF) protocol. All nodes contain single antenna and OFDM based Low Density Parity Check (LDPC) coded transmission is considered over Rician fading channel. The closed form bit-error-rate (BER) expression has been deduced for the proposed system. Performance evaluation reveals that BER of the LDPC coded ad-hoc network is better than that of non-coded ad-hoc network.
