| 摘 要： | JTIDS是美国C^3I系统的重要组成部分，具有很强的抗随机噪声和人为干扰的能力。我周边地区已装配该系统，故研究该系统的性能以及干扰方式迫在眉睫。该文简要说明了JTIDS的工作方式，从JTIDS系统的数据模型人手，完成了包括RS编码、交织编码、软扩频、MSK调制、跳频、跳时在内的整个JTIDS系统仿真。通过蒙特卡罗仿真分别得到了该系统在不同噪声环境下的误码率图，为进一步研究和干扰JTIDS系统提供了依据和数据源。

| Abstract: | JTIDS is the main component of C~3I system of America with high anti-jamming performance. It has been armed in the circumjacent countries, so it is very urgent to research its performance. The brief working process is illuminated in the paper. The simulation of whole working process, including Reed Solomon encoding,tamed spread spectrum, MSK modulation and demodulation, frequency hopped and time hopped, is introduced in this paper starting with the data model of JTIDS. Finally we get the performance of the system on noise channel, and the results can be used in further research. |
