Abstract
A spread spectrum communication apparatus comprises a correlator for correlating a received signal and a reference signal, a synchronizing circuit for synchronizing codes for spread spectrum communication according to a correlation output of the correlator, a controller for controlling a transmission power according to the output of the correlator, and a detector for detecting the output of the correlator. The synchronizing circuit synchronizes the codes according to the output of the correlator detected by the detector. The controller controls the transmission power according to the output of the correlator detected by the detector.
