摘要
美军联合战术信息分发系统(JTIDS)采用扩频、MSK调制和跳频的组合调制体制以及RS编码、交织多层纠检错编码体系,使系统具有很强的抗干扰性能。以JTIDS为背景,研究数据链通信系统的结构以及采用的抗干扰体制,分析该系统在不同信道环境和人为干扰方式下的符号误码率,并运用SIMULINK通信仿真平台对该系统在高斯白噪声及部分频带干扰情况下的抗干扰性能进行了仿真,对仿真结果进行了分析。
JTIDS adopted combined modulation methods such as spread spectrum, MSK modulation and frequency hopping,as well as various encoding methods such as RS encoding and interleaver encoding. In,this paper, the structure and the anti-jamming method of the data link communication system were analyzed, the symbol error rate of the system on different channels and jamming methods were studied. In conclusion, the anti-jamming performance of JTIDS in the Gaussian noise and partial band jamming was simulated with SIMULINK, and the result of simulation was analyzed.
