SPREAD SPECTRUM COMMUNICATION SYSTEM HAVING INTERFERENCE WAVE CARRIER DETECTING FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a spread spectrum communication system having interference wave carrier detecting function, which detects the existence of an arrival wave by comparing relative intensity of the arrival wave with the threshold. SOLUTION: This spread spectrum communication system is provided with a means for dividing time slots (ts) for receiving a communication wave and time slots (tn) for receiving the arrival wave, except a communication signal on a time axis, a means for detecting the signal intensity of the time slots (ts) for receiving a signal and radio wave intensity of the time slots (tn) for receiving the arrival wave except the signal, a means for detecting the relative intensity of the arrival wave except the signal to receiving signal power, and a threshold setting means for setting the threshold for judging existence of the arrival wave from the detected relative intensity.
