PSEUDONOISE SEQUENCE CORRELATOR AND METHOD FOR CORRELATING PSEUDONOISE SEQUENCES

摘要

A PN(Pseudo Noise) sequence correlator and a method for correlating pseudo noise sequences are provided to obtain a reliable PN sequence correlation value by synchronizing correctly a received signal within a short period. A plurality of taps(171) stores temporarily received data and outputs the stored data. A PN sequence generation unit(160) generates PN sequences corresponding to the taps. A plurality of first multipliers(174) produce correlation valves of composition data of the PN sequences and output data of the taps. Two or more block adders(175) divide the correlation values into two or more block units and sum up the correlation values corresponding to block units. A correlation multiplier(177) is used for multiplying the sum of the correlation values of block units.
