Power Allocation for Channel Estimation and Performance of Mismatched Decoding in Wireless Relay Networks

This paper is concerned with power allocation (PA) among the source and the relays of wireless relay networks to minimize the mean-square error (MSE) of the channel estimation when distributed space-time coding (DSTC) is applied. The optimal PA scheme is numerically obtained by means of geometric pr...
