Abstract
Symbol mixing across multiple input multiple output (MIMO) parallel channels is disclosed. Each data symbol is transmitted over an effective channel with a weighted sum of the singular values associated with all spatial channels. By averaging the singular values, there is less of a penalty associated with the choice of modulation and coding on the data symbols, since all transmitted symbols experience roughly the same signal to noise ratio (SNR) in transmission.
