Abstract

Performance of a single relay-based cooperative communication system in a wireless network is analyzed in this article. A single relay equipped with a single antenna employs a hybrid relay scheme. Based on the channel condition, either amplify or forward (AF) or adaptive decode and forward (ADF) scheme is employed in hybrid mode, which permits switching between the above mentioned dualistic schemes. The performance of the hybrid relay scheme has been examined in terms of symbol error rate (SER), outage probability and optimal power distribution for uncoded cooperative communication. A closed-form depiction for SER and outage probability for M-PSK signal has been derived, where the relay and the destination are considered to perform MRC combining of the message.
