Three different TDMA-based Protocols for distributed coding with DF relaying

In this paper, we consider three different time-division multiple-access based Protocols for distributed convolutional-based coded cooperative networks. Protocols I, II and III convert the spatially distributed antenna system into effective multiple-input multiple-output (MIMO), single-input multiple-output (SIMO) and multiple-input single-output (MISO), respectively. The main focus will be on the problem of relay channel coding when using decode-and-forward (DF). In the DF mode, the received signal from the source node must be demodulated and decoded prior to retransmission. We analyze the spatial diversity performance of the various protocols for distributed convolutional-based coded cooperative and find that full spatial diversity is achieved by certain protocols. An upper bounded expressions has been derived for the bit error rate on the assumption that the modulation scheme used is binary phase shift keying (BPSK). The efficacy of the three TDMA-based Protocols using distributed convolutional-based coded cooperative has been demonstrated by several numerical and simulation results.
