Abstract :
Relaying diversity techniques in wireless networks are known for their attractive performances. According to Adaptive Demodulate-and-Forward (ADmF) relaying, each relay demodulates and retransmits the received signal from the source to the destination, if the received Signal-to-Noise-Ratio (SNR) exceeds a required threshold. The destination uses the Maximum-Ratio-Combining (MRC) technique to combine the received signals. In this work, Binary Error Probability (BEP) analysis of selective ADmF two-hop relaying is provided. A new accurate BEP expression is derived for symmetric schemes with increasing number of relays. To illustrate the accuracy of the proposed theoretic BEP, a selection of simulation results is used.
