Abstract:
1. A method implemented in a multiple-input, multiple-output (MIMO) wireless communication system, comprising: transmitting a plurality of data streams from a first station to a second station over a plurality of antennas, wherein blocks of data from each of the plurality of data streams are permuted by transmitting different blocks of data from each data stream over different ones of the plurality of antennas, wherein each data stream is encoded and modulated based on a data rate for the data stream prior to transmission; inversely permuting the plurality of data streams at the second station; determining a quality metric for each of the plurality of data streams at the second station based on the different blocks of data for each data stream being permuted and transmitted over different ones of the plurality of antennas; determining a condensed quality metric at the second station based on the quality metric for each of the plurality of data streams; and transmitting the condensed quality metric from the second station to the first station.
