  • Data sequence detection in band-limited channels using two stream detector architecture
    Patent number: 8810950
    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.
