Abstract:
1. A method for detecting a data sequence, comprising: generating a first sample stream, wherein the first sample stream is a time-sequenced digital signal associated with samples of an analog signal; interpolating the first sample stream to generate a second sample stream, wherein the second sample stream has a phase that is different from a phase of the first sample stream; equalizing the first sample stream to generate a first equalized sample stream; equalizing the second sample stream to generate a second equalized sample stream; processing the first and second equalized sample streams to estimate the second equalized sample stream; filtering the first equalized sample stream to generate a first set of noise sample streams; filtering the estimated second equalized sample stream to generate a second set of noise sample streams; diversity combining the first set and second set of noise sample streams to generate a set of combined noise sample streams; and detecting a data sequence using the set of combined noise sample streams.
