Abstract
The letter describes an all-digital, noncoherent demodulator suitable for the detection of CPFSK and PSK signalling schemes. A single A/D convertor demodulates the input signal and generates baseband in-phase (I) and quadrature (Q) signals. The I and Q signals are then processed with sine and cosine detectors to produce AFC information and the regenerated transmit data.
