Abstract :
A decision feedback mechanism which can partially eliminate ISI is applied to 1-bit and 2-bit differential detectors. The differential detectors using decision feedback are compared with the conventional detectors in AWGN, static multipath, Rician multipath, and co-channel interference channels. The result shows that the decision feedback mechanism has interference resistance capability. Among all the detectors, the 2-bit differential detector with feedback has the best performance in all the channels
