METHOD FOR REDUCING TRANSMISSION ERROR

摘要

PROBLEM TO BE SOLVED: To provide a communication system that corrects errors generated during signal transmission prior to transmission in a digital Code Division Multiple Access (CDMA) communication system.SOLUTION: A digital spread spectrum communication system calculates phase errors and frequency errors in a received signal from an opposite communication party during communication, and pre-corrects the phase errors and the frequency errors of the signal prior to transmission to the opposite communication party.
