Optimum nonconcurrent digital multi-h signaling

The problem of nonconcurrent detection of multi-h CPM signals received over AWGN channel is considered. Receiver structures for show- and fast-fading cases are presented. Employing the well known union and Average Matched Filter (AMF) bounds the error rate performance of the optimum noncoherent receiver is estimated. Through minimization of these bounds optimum multi-h schemes are determined. The results reveal that there seems to be no apparent advantage in power in going for multi-h schemes relative to single-h schemes for the case of noncoherent detection.
