摘要：

We show that a finite impulse response and multi-input-multi-output (FIR-MIMO) system with colored input is blindly identifiable up to a permutation and scaling using the second order statistics (SOS) of the system's output if a) the system function is irreducible, and b) the input signals are uncorrelated from each other and have distinct power spectra, Condition a) is weaker than several conditions reported previously, It suggests a further potential of developing more robust blind algorithms.
