Abstract

We consider the problem of simultaneous estimation of the channel state information (CSI) of several transmitters that use orthogonal space-time block codes to communicate with a single receiver. Based on the generalizations of the Capon and MUSIC techniques, we propose two novel algorithms to estimate multiuser MIMO channels. These algorithms estimate the subspace spanned by the user channels blindly and use only a few training blocks to extract the users CSI from this subspace.
