Bit error rate of two-user cooperation over the uplink scheme frequency selective Rayleigh fading channel is presented in this paper. The time division multiple access (TDMA) scheme and the half-duplex mode of transmission are assumed. The network architecture is defined as symmetrical structure. We analyze the bit error rate of BPSK two-user cooperation in various relaying protocols where the perfect channel state information is available at the receiver. The relaying protocols are considered as amplify-and-forward, decode-and-forward, selection, and incremental relaying. We investigated the effects of various interuser SNRs on the performance. The result shows that the higher interuser SNRs, the better bit error rate performance. From the bit error rate performance comparison of all relaying protocols illustrates that the incremental relaying protocol give the best performance. This is the result of limited feedback in the incremental relaying from the destination yield a great improvement on the system performance.
