BER performance of continuous phase digital angle modulation in aeronautical mobile radio channels

Abstract

The bit error rate (BER) performance of continuous phase digital angle modulation is theoretically analyzed in the aeronautical mobile radio channel by applying the Pawula theorem to the channel stochastic model that was developed by the author (42nd IEEE Veh. Technol. Conf., 1992). These digital angle modulation techniques include M-ary frequency shift keying (FSK), M-ary differential phase shift keying (DPSK), and constant envelope partial response continuous-phase modulation (PRCPM) techniques such as Gaussian minimum shift keying (GMSK). The BER results show that multipath fading and Doppler shifts in the aeronautical mobile radio channel degrade the probability of error.<>
