Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  consider the problem of combining the signals received from a decode-and-forward relay with those received from the source. As an alternative to the high-complexity maximum-likelihood combining strategy,  propose a bit-wise combining strategy in which the received signals are first converted to log-likelihood values before being combined.  show that, subject to the bit-wise constraint, the optimal combining strategy for binary alphabets — minimizing the probability of error — applies a sigmoidal nonlinearity to the relay log-likelihood values before adding to the source log-likelihood values. Unlike the maximal-ratio combining strategy, which has no diversity for the Rayleigh-fading decode-and-forward relay channel, the proposed strategy exhibits the maximum diversity order of two.
