Abstract:

This paper is on the bit error probability (BEP) of opportunistic decode-and-forward (DF) relaying with coded cooperation, where cooperation diversity is achieved through both channel coding method and spatial diversity of relay selection. Codewords are partitioned into two parts which are source's data and parity, these are transmitted from source's antenna or selected relay's antenna. In this scheme, relay selection is performed in relay subset which consists of relay nodes that successfully decode source's data and parity is transmitted from selected relay node's antenna. If all the relay nodes are fail to decode source's data the source transmits its parity to the destination instead of the relay node. We derive the closed-form of bounds on BEP of this scheme based on Viterbi's upper bound. These results illustrate diversity gain with multiple relay nodes in coded cooperation and present the performance analysis of proposed scheme in numerical results.
