Optimal Estimator-Detector Receivers for Space-Time Block Coding
2004
International Symposium on Information Theory (ISIT)
Most space-time coding schemes can be classified either as non-coherent or coherent. In this paper we prove that optimal non-coherent 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.
