The Design And Implementation Of A Ds/Fh Receiver

Frequency-Hopping/Direct-Sequence Spread Spectrum is a way of communication combined Frequency-Hopping Spread Spectrum with Direct-Sequence Spread Spectrum. It is good at anti-jamming and disguises the signal. Therefore, it can be acted as the wartime emergency communications. The DS/FH communication impressed people during the Gulf War. It can be expected that the DS/FH emergency communication will play a vital role on the IT-based warfare in the future.Focused on the demand that a satellite receiver should be working well while the working circumstance is complicated and suffered from different jamming, this issue has analyzed the DS/FH communication system, explored the theory of DS/FH, especially had a deep research on the technology of acquisition and track, then designed a DS/FH communication system, including the receiver and the test equipment, and then tested the system.
