摘要: A method and apparatus for improved offset frequency estimation includes in a first embodiment receiver (100) coherent reception of signal having known reference information, the including an extractor (106) extracting information (107) from signal, estimator (110). The (110) filter (121) filtering outputting filtered sequence; correlator (122, 124) correlating sequence against predetermined to form correlation values; peak detector (126) determining estimate (131) values. Other embodiments are also shown.
