In order to enable multiple input-multiple output (MIMO) equalization, including as an example minimum mean-squared error (MMSE) MIMO equalization, to be implemented using a conventional QR decomposition, it is beneficial to force the noise variance of each of the channel outputs to be equalized. Embodiments scale the channel outputs in order to create an effective channel whose outputs have approximately the same noise variance. Embodiments comprise systems and methods for a channel outputs scaler to apply at least one scaling factor to each channel output of a channel outputs vector to thereby equalize the noise variance among the channel outputs.
