Abstract
A method for determining filter coefficients for a mismatched filter is disclosed. The method includes generating a code sequence having a code length, determining a length of the filter, and performing a modified least mean squares (LMS) algorithm. The length of the filter corresponds to coefficients of a transfer function of the filter, and the length of the filter is not equal to the code length. The filter coefficients are iteratively adjusted in the LMS algorithm until an error signal for each of the filter coefficients is below a threshold value.
