Abstract:
1. An apparatus comprising: a first main channel estimator operable to produce a main channel estimate from input samples of a communication signal; a main signal estimator operable to produce an estimated main signal from the main channel estimate and a known sequence; a first combiner operable to subtract the estimated main signal from the input samples; a data recovery module operable to recover disturber channel data from an output of the first combiner; a disturber channel estimator operable to produce a disturber channel estimate based on the output of the first combiner and the recovered disturber channel data; a disturber signal estimator operable to produce an estimated disturber signal from the disturber channel estimate and the recovered disturber channel data; a second combiner operable to subtract the estimated disturber signal from the input samples; a second main channel estimator operable to produce an improved main channel estimate based on an output of the second combiner; and an equalizer processing module operable to equalize the input samples using coefficients determined using the improved main channel estimate, the equalizer processing module comprising:
