A demodulator (16) for use in a receiver for transmission systems is adapted to demodulate received signals according to a coherent principle in a first mode and to demodulate received signals according to a non-coherent principle in a second mode. The demodulator comprises a differential detector (18), an equalizer (21) and a switch (19) adapted to couple the received signals directly to the equalizer (21) in the first mode of the demodulator and to couple the received signals to the equalizer (21) via the differential detector (18) in the second mode of the demodulator. |
