Abstract — Time Division Multiple Access (TDMA) amplify and forward based protocols have been investigated previously by various researchers. However, the gap is still there to investigate the performance of these protocols using inter-relay communication in order to improve the diversity order at destination over Rician fading channel. Therefore, the aim of this paper is to propose TDMA based amplify and forward three time slot protocol with inter-relay communication over Rican fading channel. The proposed protocol is also investigated for various relay locations in order to optimize the best relay locations in terms of less bit error rate (BER). It is concluded that the proposed amplify and forward three time slot protocol (PAFP) perform better in terms of low BER values as compared to previously proposed amplify and forward (PPAF) two time slots and three time slots protocols. Moreover, PAFP shows better results as compared to PPAF three time slots protocol in terms of less BER values when the inter-relay distance is minimum Index Terms — Cooperative inter-relay wireless
