High Order Modulation for Underwater Acoustic Communication Based on Chirp-Carrier

摘要：

　　The advantages of Chirp Spread Spectrum make it suitable for the study of underwater acoustic communication.Binary Orthogonal Keying modulation was widely used,though,it has a low transmission rate,while QBOK may cause phase ambiguity.Therefore,the π/4-DM-DQPSK high order modulation was introduced to solve the problems.In this paper,the basic principles of π/4-DM-DQPSK communication system was presented,and the system BER performance in AWGN,pool multipath,Bellhop multipath,and ocean multipath was analyzed.It turns out π/4-DM-DQPSK system has good BER performance in the simulation experiment.
