摘要： A method (200) for synchronizing a receive sequence with a known transmit sequence includes: compressing (201) a replica of the known transmit sequence from a length N to a reduced length B, the length N being a multiple of the reduced length B, by applying a B-by-N compression matrix Ψ to the replica to obtain a compressed replica of the reduced length B, wherein the compression matrix Ψ comprises a plurality of shifting matrices each of the shifting matrices depending on a first compression parameter p that is an integer ratio of the length N and the reduced length В and a second compression parameter α that is an angle between 0 and 2 π ; compressing (202) the receive sequence from the length N to the reduced length В by applying the B-by-N compression matrix Ψ to the receive sequence to obtain a compressed receive sequence of the length B; and multiplying (203) the compressed replica with the compressed receive sequence in frequency domain to obtain a compressed product sequence, wherein a time-domain transform of the compressed product sequence indicates a correlation between the receive sequence and the replica of the known transmit sequence.
