Abstract

Compared with the conventional one-way counterpart, two-way cooperative communications can significantly improve spectrum efficiency. When no channel state information is available at the receivers, we propose optimal non-coherent detector based on maximum likelihood rule for frequency-shift keying modulated two-way amplify-and-forward (AF) cooperative communications in Rayleigh fading channels. We have also theoretically derived the bit-error-rate performance lower bound of proposed two-way AF cooperative communications.
