摘要: An Orthogonal Frequency Division Multiplexing (OFDM) receiver detects and corrects sampling offsets in the time domain. The OFDM oversamples (62) a training sequence or symbol received signal, correlates (64) oversampled with stored copy (66) of truncated version sequence, locates correlation peak (70), derives offset (72) by calculating difference magnitude samples vicinity peak.
