Abstract :
This letter is to correct the incorrect optimal relay coefficient at the k-th relay derived in [1] for an amplify-and-forward (AF) wireless relay network under received power constraints. While the trends remain the same, with the correct optimal relay coefficient in this paper, nonnegligible improvement, e.g., about 0.8 dB at BER = 10-7, can be achieved.
