Abstract :
In this paper, we present a closed-form solution for blind multiple-input multiple-output (MIMO) finite impulse response (FIR) channel estimation driven by colored sources whose second-order statistics (SOS) are assumed to be known a priori. The proof for the uniqueness of the system solution is provided. Numerical simulation results are presented to illustrate the performance of the proposed algorithm.
