摘要: Continuous phase modulation (CPM) encompasses a class of signaling schemes that conserve and reduce signal energy bandwidth at the same time. Furthermore, signals in this have constant envelope therefore are very attractive radio channels employing low-cost non-linear power amplifiers. Notwithstanding these favorable features, current CPM applications still limited to few simple (basically, MSK its generalizations) because implementation complexity synchronization problems [1]. Research efforts under way advances areas expected near future.
