Modulation and Information Frame of DS-FFH/MSK Hybrid Spread Spectrum TT&C.

Abstract: A DS-FFH/MSK hybrid spread spectrum TT&C system is designed to improve the anti-interception and antijamming performance of TT&C system. MSK modulation signal is selected for hybrid spread spectrum TT&C system upon analysis and comparison. A synchronization method of short code guiding long code is discussed. The frame format of complete information and data of the hybrid spread spectrum is designed. The simulation results indicate that acquisition time can be greatly reduced, which is perfectly applicable to the TT&C application environment. [Copyright &y& Elsevier]
