Abstract :
This paper investigates a performance of differentially encoded cooperative communications achieving full rate in three-user cooperation scenario with a fixed amplify-and-forward protocol. Tight upper and lower bounds on an averaged bit error rate (BER) for such system are also developed. These proposed bounds significantly reduce computational complexity of evaluating an exact averaged BER. Simulation results show that the proposed bounds are tight to the exact one in fairly-high signal to noise ratio (SNR) regimes
