Abstract
A method for data sequence detection includes generating a first sample stream, equalizing the first sample stream to generate a first equalized sample stream, and buffering the first equalized sample stream. The first sample stream is interpolated to generate a second sample stream. The second sample stream is equalized to generate a second equalized sample stream. In a first processing path, the samples of the buffered first equalized sample stream are filtered using a first noise predictive filter bank to generate a first set of noise sample streams. In a second parallel processing path, the samples of the buffered first equalized sample stream are interpolated using a second interpolation filter to generate an interpolated sample stream and the interpolated sample stream is filtered to generate a second set of noise sample streams. The first equalized sample stream and the second equalized sample stream are processed to generate adapted filter coefficients for the second interpolation filter. The first and second set of noise sample streams are diversity combined to generate a set of combined noise sample streams. A data sequence is detected using the set of combined noise sample streams.
