Decoding MIMO space time code symbol-pairs

摘要

A MIMO wireless communication system and method reduces the number of recursive operations when decoding received data symbols by decoding the data symbols in pairs rather than on a per symbol basis. Decoding in pairs is facilitated by the determination that errors between selected pairs of data symbols are uncorrelated and identically distributed with a determined variance. Additionally, the system and method can order the pairs and provide decoding rules that result in an insignificant loss of performance for a wide range of signal-to-noise ratios (SNRs). Furthermore, the system and method exploit the structure of the error covariance matrix to reduce computational demands.
