Title: Digital demodulation utilizing frequency equalization

Abstract: A method and apparatus for digital demodulation for use in a wireless communication device include processing that begins by performing a fast Fourier transform to convert a plurality of time domain symbol components representing inbound data into a plurality of frequency domain symbol components. The processing continues by frequency domain equalizing at least some of the plurality of frequency domain symbol components based on a dynamic compensation control signal to dynamically compensate for adverse transmission characteristics of the plurality of time domain symbol components. The processing then continues by generating a plurality of estimated symbols and a plurality of error values for the plurality of compensated frequency domain symbol components. The processing then continues by generating the dynamic compensation control signal based on at least one of the plurality of error values, the plurality of frequency domain symbol components and the plurality of compensated frequency domain symbol components.
