Blind Signal Separation and Equalization with Channel Order Disparity
Cheng Wang, Bin Yang · 2019
This paper deals with the problem of blind source separation in multiple-input multiple-output finite impulse response channels. According to multipath delay spread range of signal, we develop the subspace for equalization and large multipath delay spread interferences cancellation using the shifted versions of data covariance matrix. Then a minimum mean square error equalizer is proposed relying on the considered subspace for signal recovery. Both theoretical analysis and simulation examples confirm the effectiveness of proposed technique in desired signal separation and equalization.
