Weighted subspace method for FIR multichannel estimation
Fangjiong Chen, Sam Kwong, Gang Wei · Electronics Letters · 2002
A blind finite impulse response (FIR) multichannel estimation using the weighted signal subspace method is presented. Using this approach, it is shown that the noise subspace can be represented by the channel parameters. A weighted matrix of the signal subspace method is applied to achieve a deterministic estimation for FIR multichannels. Simulation results show the efficiency of the proposed algorithms.
