Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: With reference to the typical three-node amplify-and-forward (AF) relaying setup, where a single relay assists the communication beten a source terminal and a destination terminal,  investigate the effect of outdated channel state information (CSI) at the relay on the overall performance. In particular,  consider CSI-assisted (i.e., variable-gain) AF relaying and derive expressions for the outage and the error probability for the case where the relay gain is adapted based on outdated estimates of the source-relay channel, when operating over Nakagami-m fading. The obtained expressions are functions of the scale and shape fading parameters, as ll as the correlation coefficient beten the actual source-relay channel and its corresponding estimate. Numerical results reveal a considerable degradation of the overall performance, when CSI acquisition is not perfect.
