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.
