ABSTRACT:
A method of creating an finite impulse response (FIR) filter adapted to the channel impulse response of a time-dispersive transmission channel includes the steps of providing several FIR sub-filters in parallel, selecting the tap locations of each sub-filter, determining the sub-filter tap coefficients in such a manner that the output impulse responses of the sub-filters are partially or entirely orthogonal with respect to each other, and creating an FIR filter by weighting the combination of parallel sub-filters to create a FIR filter.
