| Abstract: | 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. |
