Function implementing the Wiener-Hopf method to determine the least squares solution for an equalizer, implemented as an FIR filter. Given a known transmit sequence (either through use of a training sequence or receiver decisions) and a know received copy of the same sequence, this function will determine the coefficients for an FIR filter (equalizer) that will compensate for all channel distortions, in a least squared error sense. Passing the received sequence through the equalizer will recover the transmitted sequence. Applications are in wireless communications and sound processing.
