Abstract
A continuous phase shift modulation system wherein, for each of the in-phase and quadrature components, adjacent half-cosine pulses of the same polarity are joined by a continuous transition modulation signal which maintains continuity of the waveform and at least its first derivative. When this occurs, the other component signal is adjusted to maintain constant the vector sum of the component signals.
