Abstract

In this paper, we analyze the optimal power allocation for the multihop linear nonregenerative relay cooperative system. The expression for the end-to-end SNR is deprived in terms of power allocation factors to each node and the channel state information, based on which, we obtain the optimal power allocation factors for each nodes by maximizing the end-to-end SNR subject to the total power constraint. Numerical simulations show that the theoretical prediction matches the simulation, and dynamic power allocation outperforms the fixed power allocation scheme.

Keywords: Terms—multihop linear relay networks amplify-andforward end-to-end SNR power allocation
