Acquisition Performance Analysis of a Synchronization Scheme of DS/FH Hybrid Spread Spectrum Signals for TT&C

摘要：

A synchronization scheme of DS/FH hybrid spread spectrum signals based on fast frequency identification is proposed, for high dynamic characteristic of signals in TT&C system. On basis of providing the mathematical model of synchronization process of the signal, three-dimensional mean acquisition time expression as well as probabilities of detection and false alarm of acquisition system with PN phase error, Doppler frequency and AWGN, is derived. Based on numerical simulation of threedimensional acquisition performance with the DSSS mode of matched filter in time domain and multiple channels in frequency domain, impact of parameters of the signal and the acquisition system on acquisition performance is analyzed. Theoretical derivation and simulation results provide theoretical basis and practical reference for signal design as well as parameters selection of the acquisition system.
