Outage performance of multi-hop cooperative diversity system
Zhang Chun-pin · Journal of Computer Applications · 2013
An approximate outage probability formulation and diversity order were derived for multi-hop diversity system employing Decode-and-Forward(DF) relaying in high Signal-to-Noise Ratio(SNR).And a modified multi-hop Selective Decode-and-Forward(SDF) protocol was proposed to overcome the limitation of space full diversity system unemploying DF relaying,the source node resended the information when the relay could not decode information correctly.An approximate outage probability formulation and diversity order were deduced for SDF protocol in high SNR.The theoretical analysis and simulation results show that the SDF protocol can improve transmission performance and achieve the full space diversity contrasted with DF protocol.
