Patent ID: 8472543

Claim:
A method for communicating information is in a wireless communication system, the method comprising: performing by one or more processors and/or circuits in a multiple input multiple output receiver system that utilizes maximum likelihood detection: computing a channel realization matrix based on a plurality of spatial stream signals that are concurrently received via a plurality of receiving antennas; computing a plurality of channel quality index values based on said computed channel realization matrix, the plurality of channel quality index values including a first channel quality index value and a subsequent channel quality index value, wherein: the first channel quality index value is computed, at least in part, by generating a singular value decomposition of the channel realization matrix, and the subsequent channel quality index value is computed based upon a symmetrical relationship between the first channel quality index value and the subsequent channel quality index value; and selecting one or more coding rates based on said computed plurality of channel quality index values.
