Tracking algorithm for equalizers following variable gain circuitry

A receiver for processing signals transmitted through a dispersive medium and received at a plurality of diversity channels, said receiver comprising

• receiving means responsive to the transmitted signals received from said dispersive medium for providing received signals at each said diversity channel;
• adaptive equalizer circuitry responsive to said received signals for providing a combined adaptively weighted equalizer output signal, said equalizer circuitry including
• a plurality of weighting sections responsive to time delayed received signals and to a plurality of adaptive weighting factors for providing a plurality of adaptive weighted signals;
• and
• means for combining said plurality of adaptive weighted signals to provide said combined adaptively weighted equalizer output signal;
• means for deriving an error signal in response to said combined adaptively weighted equalizer output signal and to an adjusted reference signal;
• means responsive to said error signal and to the adaptive weighted signals at each weighting section of said adaptive equalizer circuitry for generating said plurality of weighting factors for use in said weighting sections to provide said plurality of adaptive weighted signals;
• means responsive to a signal from said adaptive equalizer circuitry, said signal having an amplitude which is an estimate of the amplitude of said adaptively weighted equalizer output signal, for generating a scale factor;
• and
• means responsive to a non-adjusted reference signal and to said scale factor for providing said adjusted reference signal which is adjusted by said scale factor for use in deriving said error signal.
