Abstract: “The opportunistic relaying scheme with the selection of antenna at source is the best alternative to get many of the benefits of MIMO [1]. In such a scheme, the best relay as well as best antennas at source can be selected for communication. Here, we will introduce the opportunistic amplify and forward relaying with direct link using antennas selection at source only. Under assumption of Rayleigh fading channel, in this proposed scheme the exact BER (bit error rate) performance will be analyzed and observed that the increasing antennas is a better option as compared to relays”
