摘　　要：基于MSK调制的直扩/跳频混合扩频通信系统不仅具有较高的抗干扰性和保密性,还具备较好的频带利用率和误码性能。结合直扩/跳频混合扩频系统和MSK调制的原理和特点,设计了一种基于MSK调制的直扩/跳频混合扩频通信系统,给出了系统构成、工作原理和相关算法,并搭建硬件平台对其解调性能进行仿真分析,得出系统采用部分匹配滤波法进行解调是比较可行的结论。DS/FH hybrid spread spectrum communication systems based on MSK modulation not only has high anti-jamming and confidentiality,but also has high bandwidth efficiency and error performance. In combination with the principle and charac-teristics of DS/FH hybrid spread spectrum communication systems and modulation of MSK,a kind of DS/FH hybrid spread spec-trum communication system based on MSK modulation is designed. The structure,working principle and related algorithms are provided,and the hardware platform for simulated analysis of the demodulation performance is established. It is obtained that using partial matching filter method to demodulate is feasible.
