JTIDS signal simulation based on Simulink

Abstract:

By studying the key technologies of Joint Tactical Information Distribution System(JTIDS)，and utilizing Simulink software，this study realized the source error control coding. By using 32 bit Cyclic Code Shift Keying(CCSK) code-word S0 to establish spread spectrum space, the tamed spread spectrum was completed. The random transformation of 51 frequency points was achieved with VCO module and the link simulation of JTIDS was prosecuted. The anti-jamming performance of this system was analyzed in the Additive White Gaussian Noise(AWGN) channel and jamming environment，which laid the foundation for the study of effective jamming to this system.
