Abstract :
The dimensionality of a CPM signal set can be determined by finding a basis for the chips of the underlying phase pulse. It is shown that the number of matched filters needed for optimum detection depends primarily on the number of elements in this basis. Thus, by using CPM schemes with a small basis, optimum detection with a large signalling alphabet and a long frequency pulse is feasible. However, the bandwidth properties of these schemes are rather poor compared to pulses with a larger basis
