ABSTRACT:
A differential coherent modulation and demodulation method and apparatus non-coherently modulates (201) a data stream to generate non-coherently modulated data. The non-coherently modulated data is phase modulated (215) with a supplementary signal (211) to generate coded data. The coded data is then transmitted. A receiver (301) then receives the coded data. A non-coherent demodulator accepts the received coded data as input and demodulates the coded data to provide the original data and the supplementary signal (327).
