Patent ID: 6947715

Claim:
A communication receiver that employs vector orthogonal frequency division multiplexing, comprising: a communication receiver that receives a plurality of data signals that is transmitted via a multi-path communication channel; and wherein the communication receiver is operable to estimate noise for each path within the multi-path communication channel; the communication receiver is operable to estimate cross-coupled noise between each of the paths within the multi-path communication channel; the communication receiver is operable to generate a correlation matrix having elements that comprise the noise estimates of each path within the multi-path communication channel and the cross-coupled noise between each of the paths within the multi-path communication channel; the communication receiver performs square root factorization to the correlation matrix to generate a factorized correlation matrix; and the communication receiver employs the factorized correlation matrix to combine the plurality of data signals into a single signal, the single signal comprising a beam form soft decision.
