ABSTRACT:
A receiver for a spectrum spread communication system capable of eliminating a deterioration in receive quality due to fading by multipass. A signal of which a spectrum is spread by a direct spread modulation system is transmitted from a transmit side unit. A receive side unit is provided with a plurality of receive antennas, through which receive signals are fed to receiver circuits, followed by conversion of each of the signals into an intermediate frequency signal. Then, the signal is fed to a signal intensity measurement circuit and sampled by a clock n (n: an integer) times as high as a chip frequency, resulting in an intensity thereof being measured. Depending on results of the measurement, a selection signal is fed to a path switching circuit, resulting in one of outputs of the receiver circuits being selected, which is then fed to a direct spread demodulation circuit.
