| 摘 要： | 本文将ＧＭＳＫ调制引入到跳频通信中，以利用ＧＭＳＫ高频谱效率的特点在跳频通信中实现高速数据传输。首先给出了采用ＧＭＳＫ调制的慢跳频通信系统ＳＦＨ－ＧＭＳＫ原理与实现方法，提出了基本的数学模型。在此基础上，获得了在不同的跳频间隔长度下ＳＦＨ－ＧＭＳＫ信号的频谱图。随后给出了基于Ｖｉｔｅｒｂｉ算法的ＳＦＨ－ＧＭＳＫ信号的非相干解调方案，并通过计算机模拟获得了该解调方案的误码性能。

| Abstract: | In this paper,GMSK is introduced into the frequency hopping communication system to implement high rate data transmitting in frequency hopping communication The principle and system mathematic model of the SFH GMSK system is first presented and the power density spectrum of the SFH GMSK signal are obtained Then the noncoherent demodulate method based on the Viterbi algorithm is discussed The performance of this algorithm is analysed through computer numerical simulation |
