1. A method of complex-valued path gain estimation in a receiver, the method comprising the steps of:

  • approximating the path gain as a function of average path gain and rate of change of path gain over a block of B samples;

    generating the path gain estimation over the block of B samples utilizing the matched filter outputs and soft decisions made on data symbols related to the block of B samples;

    modifying the generated path gain estimation by first and second factors to produce first and second adjustment factors; and

    modifying the average path gain utilizing the first adjustment factor and modifying the rate of change of path gain utilizing the second adjustment factor to produce an updated path gain approximation.
