Abstract
A radio receiver apparatus for receiving a spread spectrum signal in which a signal derived through a level detection of a signal demodulated by a correlative demodulator and a signal obtained by extracting a signal component of a synchronous frequency from a reception synchronizing clock are combined to thereby generate a reference signal having a level which changes in accordance with change of the detected signal, and by comparing the detected signal with the reference signal, the received signal is discriminated.
