A Fast Synchronization Method of DS/FH Hybrid Spread Spectrum TT&C System

摘要：

A fast synchronization method of short code guiding long code is discussed in a DS/FH hybrid spread spectrum TT&C system. The acquisition of frequencyhopping short code is achieved with matched filter and the acquisition of direct-sequence spread spectrum short code is achieved with FFT based on code sequence and on carrier. The simulation results indicate that acquisition time can be greatly reduced by combining the system with carrier-based FFT, code sequence-based FFT algorithm and matched filter, which is perfectly applicable to the TT&C application environment.
