1. A system for calculating radio frequency (RF) wireless channel properties for digital communications over a wireless channel, comprising:

  • a receive processor for receiving information over said wireless channel, converting the information to digital signals, and processing the digital signals;

    a channel estimator for calculating a first channel property matrix from said digital signals;

    a storage unit containing a plurality of previously computed channel property matrices;

    a storage lookup unit operatively coupled to said storage unit that selects at least one second channel property matrix from said plurality of previously computed channel property matrices;

    a function for determining whether said first channel property matrix is usable with said at least one second channel property matrix or said at least one second channel property matrix is usable with said first channel property matrix for improving the accuracy of the calculated RF wireless channel properties;

    a combination unit for generating a composite channel estimate based on said first and said at least one second channel property matrix; and

    an equalizer for using the composite channel estimate to process baseband signals supplied from a plurality of baseband processors to reverse effects of the wireless channel on signals carrying the information over the wireless channel.
