Multichannel blind identification: from subspace to maximum likelihood methods

Lang Tong, S. Perreau
1998 Proceedings of the IEEE  
A review of recent blind channel estimation algorithms is presented. From the (second-order) moment-based methods to the maximum likelihood approaches, under both statistical and deterministic signal models, we outline basic ideas behind several new developments, the assumptions and identifiability conditions required by these approaches, and the algorithm characteristics and their performance. This review serves as an introductory reference for this currently active research area.
