JTIDS链路性能分析与仿真

Analysis and Simulation of the Link Performance of JTIDS

从链路层的角度出发,介绍了美军联合信息分发系统(JTIDS)的技术体制;并对其传输性能进行了分析;在用SPW软件建立的系统的链路仿真平台上,系统在不同条件下,例如高斯白噪声、多网干扰、点频及部分频带干扰以及非理想同步,对误码性能进行了仿真测试;最后,还对JTIDS系统的抗干扰能力进行了评估。

From the link-level point of view, the technical structure of the Joint Tactical Information Distribution System (JTIDS) is presented and its performance is analyzed in this paper. The bit error rate (BER) simulation is tested in the different conditions, such as white Gaussian noise, multi-net interference, single-frequency interference, band- frequency interference and synchronization error, in the established link simulation platform with SPW software. Finally, based on the simulation results, anti-jamming ability is also evaluated.
