SPREAD SPECTRUM COMMUNCIATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To attain high-speed spread code synchronization by reducing a time required for searching multi path. SOLUTION: A code generating timing control circuit 21 estimates a time region, where a multi-path signal is received with high probability on the basis of generating timing information of a spread code generated for inverse spread processing of a maximum path during reception in a second correlators 16a-16n. Then the generating timing of a spread code replica is controlled so as to allow a 1st correlation 13 to receive this time region.
