Abstract

We analyse the performance of combined frequency and differential phase shift keying (2FSK/MDPSK) in the satellite mobile channel (SMC). We use two detectors in which the frequency symbol is detected by a limiter discriminator detector (LDD) and the phase symbol by a differential phase detector (DPD). The signal has a constant envelope. It is shown that this system is both power and bandwidth efficient when compared with other systems with constants envelope and noncoherent detection like LDPSK, GMSK and binary CPFSK
