Abstract :
In this paper, we developed a subspace projection method for blind MIMO FIR identification, based on fourth order statistics of the output signals. The proposed method employs a subspace projection technique to identify the channel. The method identifies MIMO channels up to a nonsingular matrix, and it does not require exact knowledge of each user´s channel order. Simulation results are included to verify our theoretical claims.
