band (e.g., high fractional [[out-of-band]] power), leading to poor [[spectral efficiency]].

Furthermore, CPM is typically implemented as a constant-envelope [[waveform]], i.e. the transmitted carrier power is constant.

Therefore, CPM is attractive because the phase continuity yields high spectral efficiency, and the [[constant- envelope]]

yields excellent power efficiency. The primary drawback is the high implementation complexity required for an optimal receiver.
