Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  present the optimum selection-combining (SC) rule for M-ary signals based on the log-likelihood ratio (LLR) in frequency-nonselective, independent and nonidentically distributed fading channels. The motivation for using the LLR in selecting the diversity branch is that it provides the reliability information of the maximum a posteriori probability decision which minimizes the probability of symbol error.  present coherent and noncoherent optimum SC rules with and without fading information that minimize the probability of symbol error. It is shown that the optimum SC rule provides a significant por gain over the conventional signal-to-noise ratio-based SC rule, and the por gain increases with an increasing number of available diversity branches and decreasing alphabet size.  also present suboptimum SC rules that require less computation, but provide a por gain close to that provided by the optimum SC rule.
