Correlation for synchronizing to long number sequences in communications systems

摘要: A correlation arrangement comprises 2k correlators each for correlating a sub-block of k symbols sequence derived from received signal wireless communications system with all possible sequences binary to produce respective one correlator outputs. For PN (pseudo random noise) synchronization, N candidate sequences, the is used select outputs as output sub-block, and selected are accumulated m sub-blocks result block mk symbols. maximum results detected providing this identified synchronization. N, k, integers. The reduces computation large values blocks.
