ABSTRACT:
A technique for generating the tap-weight coefficients for a signal dispersion cancelling filter utilizes circuitry which is responsive to received signal samples and generates a time-ordered sequence of derived signal samples. The tap-weight coefficient circuitry includes filters which operate in response to this sequence. One such filter is responsive to the derived signal samples in a first portion of the sequence after the time-order of the derived signal samples therein is reversed and another filter is responsive to the derived signal samples in a second predetermined portion of the sequence. This technique is applicable to a variety of communications systems including television and is particularly suitable for integrated circuit implementation.
