The proposed work analyzes the performance of dual‐hop relaying systems by means of the differential amplify‐and‐forward relaying method. The post‐detection selection combining reception scheme proposed in this article allows receivers to approximate existing fading gain in a branch by using previously received samples to achieve a cooperative diversity at cases that exclude the need of having explicit channel estimation. Assuming independent fading channels, tight closed‐form expressions for the system bit error rate and outage probability are ultimately derived considering Nakagami‐m fading channels and additive white Gaussian noise. Different fading parameters were used to plot simulation results.
