Abstract :
We present a closed-form solution for blind single-input multiple-output finite impulse response channel estimation driven by colored sources. The second-order statistics of the input source are known a priori. The uniqueness of the system solution is proved by exploiting the derived property of companion matrices that are constructed from the inherent structural relationship between the source autocorrelation matrices. Numerical simulation results are presented to illustrate the performance of the proposed algorithm.
