Abstract
A system and method for decoding a Multi User (MU) Multiple Input Multiple Output (MIMO) signal is disclosed. The method comprises receiving a selected symbol in a tone of an MU-MIMO signal at a mobile communication device. A channel response for the selected symbol is identified. Spatial whitening is applied to the tone and the channel response using an average of a co-user interference plus noise matrix that is averaged over a selected number of tones. Maximal ratio combining is performed for the spatially whitened tone and the spatially whitened channel response matrix to decode the selected symbol out of the spatially whitened tone.
