1. In a multiple-input multiple-output (MIMO) communication system with multipath channels, a method for processing a plurality of received symbol streams to recover a plurality of transmitted symbol streams, comprising:

  • processing the received symbol streams to provide a plurality of detected symbol streams, wherein each detected symbol stream is an estimate of a corresponding transmitted symbol stream;

    determining a metric for each of the plurality of detected symbol streams, wherein the metric considers frequency selective response of one or more transmission channels used to transmit the detected symbol stream;

    selecting the detected symbol stream associated with a best metric for recovery; and

    processing the selected detected symbol stream to recover the symbol stream and obtain data transmitted for the symbol stream.
