I7 an SS receiver, a tracking unit (43, 45, 55) tracks successive regions covering maximum correlation valus, respectively, in SS demodolated components to produce a timing signal indicative of synchronous points respectively in the regions. Responsive to the timing signal, a differential demodulator unit (33, 41, 69) demodulates the SS demodulated components at each synchronous point and at a time point which is always one symbol period later than this synchronous point. Differential demodulation is carried out in this manner so as to faithfully inversely relative to differential modulation in an SS transmitter. <IMAGE> |
