A modified phase pulse signal is proposed to analyze the effect of the shape of the phase pulse signal which exerts an influence upon the phase trajectory of continuous phase modulation (CPM). Using the minimum Euclidean distance, the 99% bandwidth, and their tradeoff, the performance of convolutional coded CPM with the modified phase pulse signal is analyzed. It is found that the power and bandwidth tradeoff of the modified phase pulse CPM is greatly improved over the conventional LREC and LRC by selecting the shape and the signal duration of the phase pulse appropriately
