Abstract
Asymptotic error probabilities for conventional and opportunistic relaying with channel estimation errors derived by Amin are erroneous. Therefore, this commentary presents the new asymptotic expressions of error probability. However, the developed optimal power allocation rules and the diversity order are unaffected by these errors in the formulations.
