A communication system and method for continuous phase modulation providing for transmission of a phase-modulated carrier having a phaseform representative of concurrently transmitted symbols. The phaseform of the phase-modulated signal is a sum of shift bi-orthogonal functions, each term in that sum being weighted by one of the overlapping symbols. The communication system and method provide full-response demodulation for the recovery of a particular symbol from among the concurrently transmitted symbols by selecting a receiving filter function shift bi-orthogonal to the transmitter filter function corresponding to the particular symbol. The communication system and method then provide for nulling, by integration over a time interval during which the particular symbol is transmitted, those transmitter filter functions that do not correspond to the particular symbol. This results in the separation of the particular symbol from the other concurrently transmitted symbols.
