Patent ID: 8705647

Claim:
A method for multi-input, multi-output (MIMO) communications, comprising: (a) equalizing an MIMO signal with an equalizer, said MIMO signal coming from a frequency-selective MIMO channel, (b) computing an equivalent MIMO channel for an equalizer output, said equivalent MIMO channel including said frequency-selective MIMO channel and said equalizer, and said equalizer output being the output of said equalizer, (c) computing a noise covariance matrix of said equalizer output according to said equivalent MIMO channel, (d) square-root decomposing said noise covariance matrix to obtain a de-correlation matrix, (e) applying said de-correlation matrix to said equalizer output to generate a de-correlated MIMO signal, and (f) applying MIMO demodulation to said de-correlated MIMO signal, whereby said de-correlated signal has de-correlated noises.
