Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: ,  present a por control method of relay for improving a channel estimation performance in amplify-and-forward (AF) relay networks over frequency-selective fading channel.  first analyze a channel mean-square error (MSE) by imposing a por control effect on a simple (LS) channel estimation. Then,  find that there is a trade-off beten the amplitude of por control and MSE performance. Moreover,  propose the optimal and suboptimal por control methods in order to resolve such a trade-off. Finally, the superiority of the proposed channel estimation with optimal por controls is verified through numerical simulations.
