A receiver for a spread spectrum communication system comprises an acquiring circuit that periodically acquires in synchronization a plurality of signals received via a plurality of paths different in route from a transmitter; a plurality of tracking circuits that track in synchronization a predetermined number of signals among the plurality of signals acquired by the acquiring circuit, respectively; a judging circuit that judges whether present and past propagation condition of the predetermined signals tracked by the plurality of tracking circuits are good or bad; a selecting circuit that selects the predetermined number of signals from the plurality of signals acquired by the acquiring circuit, based upon the present and past propagation condition of the signal judged by the judging circuit, to allow the plurality of tracking circuits to track the predetermined number of signals selected by the selecting circuit.
