ABSTRACT:
An adaptive filter that processes a sequence of input data includes a backward-looking predictive filter, which responsive to the input data and predictive filters the input data using a first set of filter tap weights and provides first predictive filtered data indicative thereof A first delay device delays the input data for a first period of time and provides a first delayed input data. A forward-looking predictive filter is responsive to the first delayed input data, and predictive filters the delayed input data using a second set of filter tap weights that are the complex-conjugate of the first set of filter tap weights, and provides second predictive filtered data indicative thereof. An adder sums the first predictive filtered data together with the second predictive filtered data and provides output data indicative thereof.
