Abstract
Most space-time coding schemes can be classified either as noncoherent or coherent. In this paper we prove that optimal noncoherent decoding can always be decomposed into a channel estimation step followed by coherent decoding step. Surprisingly the required estimators do not in general minimise the mean squared error between the estimated and actual channel.
