CPFSK schemes with modulation index , where and are relatively prime positive integers, can be represented by a decomposed model consisting of a continuous phase encoder (CPE) and a memoryless modulator (MM). The differential encoder is shown to fit well with the CPE and form a decomposed model of differentially encoded CPFSK (DCPFSK). A basic receiver structure for differentially demodulating DCPFSK is presented along with simulation results. An exact formula for the minimum squared Euclidean distance (MSED) of differentially demodulated DCPFSK is also given.enAll Right ReservedTheses / Dissertations
