Abstract :
The impact of interference on tactical data link communication system (TDLCS) can be quantitatively described through anti-jamming performance simulation. Therefore, anti-jamming performance simulation of TDLCS is of special interest. The basic structure and principle of TDLCS were introduced. And then the MSK modulation/demodulation and direct sequence spread spectrum (DSSS) techniques were analyzed. The anti-noise performance of DLCS in Gaussian white noise channel was studied. Moreover a model of TDLCS with MSK modulation/demodulation and DSSS modules based on Simulink in Matlab was developed. The simulation results were verified.
