In this letter, the performance of space shift keying (SSK) modulation is analyzed with partial amplify and forward (AF) relay selection (RS) from multiple numbers of relays and selection combining (SC) at the receiver. This scheme selects a single radio frequency (RF) chain from the transmitter to the relay using the RS as well as relay to the receiver using the SC technique. Closed‐form expression for average bit error probability (ABEP) is derived and Numerical and computer simulation results are presented with the discussion. The result derived is compared with the best RS where the best link between the transmitter to the receiver is selected with SC at the receiver. It is revealed that there is an interesting trade‐off between partial RS and best RS with SC at the receiver. However, it is shown that partial RS with SC has almost equal ABEP performance in comparison to best RS with SC with low hardware complexity.
