Blind signal separation and blind system identification of irreducible MIMO channels
Senjian An, Yingbo Hua · 2002
This paper deals with blind system identification of FIR MIMO (finite impulse response and multi input multi output) channels driven by colored signals. Based on second order statistics, a novel technique of blind identification is developed for irreducible MIMO channels. It requires a weaker condition on the input power spectra than some existing blind system identification methods and the computation is also reduced.
