A lot of excellent modulation technology has emerged as the times require, Gaussian Minimum frequency shift keying（GMSK）is one of the most outstanding technology in radio communication. It is especially used in radio and satellite communication for its nice spectrum characteristic and anti-jamming capability. At present , many communication system has employed the GMSK, for instance, the GSM, DECT. In this paper , the MSK which is the base of GMSK was introduced firstly, and then the modulation principle and methods of GMSK was analyzed, and the several differentially demodulation methods of GMSK was studied and compared emphatically, Finally using Matlab software simulate and results analysis.KeyWords：Gaussian Minimum Shift Keying；Modulation；DifferentialDemodulation；Matlab目 录第一章 绪 论........................Error: Reference source not found1.1 选题的依据及意义.............Error: Reference source not found1.2 国内外讨论现状及进展趋势.....Error: Reference source not found1.3 本课题讨论内容...............Error: Reference source not found第二章 MSK 调制与解调...
