Abstract :
A new computationally simple approach to blind decoding of orthogonal space-time block codes is proposed. Our approach estimates the channel matrix in a closed form and uses this estimate in the maximum likelihood (ML) receiver to decode the symbols. It exploits specific properties of the orthogonal space-time block codes (STBCs) and is free of most of the shortcomings of other blind space-time decoding schemes.
