Spread spectrum receiver for use in communication systems
 A spread spectrum receiver for use in a mobile communication system is provided which includes a plurality of spread spectrum demodulators, a diversity combiner, a power level detector, a correlation determining circuit, a signal combination determining circuit, and a demodulator phase control circuit. The correlation determining circuit determines correlation among input multipath signals transmitted through different transmission paths. The signal combination determining circuit selects the same number as that of the spread spectrum demodulators out of the multipath signals, which minimizes a drop in power level of a diversity combined signal outputted from the diversity combiner according to the determined correlation. The demodulator phase control circuit controls phases of demodulating operations of the spread spectrum demodulators to demodulate the selected multipath signals, respectively.
