Method and apparatus for channel tracking |
摘要 |
A method and apparatus for channel tracking is disclosed wherein pulse-shaping information is used to improve channel tracking performance. Information symbol values are prefiltered using the pulse shape information for a received baseband signal to generate a filtered waveform. The filtered waveform provides a reference signal for a medium response estimation. The estimated medium response is used with a coherent detector to detect unknown information symbols within the baseband signal. Medium response estimates can be determined for a single detected symbol sequence or for each hypothesized symbol sequence.
