摘要/Abstract

摘要： 传统的信道模拟器关注于射频信号传输的细致刻画,但在具有高动态网络拓扑的空间信息网络实时仿真中无能为力。为解决该问题,提出了一种基于模拟中频信号处理的空间信息网络仿真平台,在模拟中频仿真链路衰落、多径、多普勒、噪声、路径时延等信道特性的同时实时仿真网络拓扑的动态变化。平台支持8~128个最大20 MHz信号带宽的70 MHz模拟中频仿真节点,可灵活配置各链路类型,最大衰落深度100 dB,最大多普勒2 MHz,最大传播延时2 s。可作为空间信息网络设计规划的有力支撑工具。

Abstract: To solve the problem of real-time simulation of spatial information network with high dynamic network topology, a real-time simulator based on the IF signal processing is proposed. Compared with traditional channel simulator, it supports both the channel transmission characteristics like channel fading, Doppler shift, noise, and path delay, and the real-time simulation of dynamic network topology changes. The simulator supports 8~128 70 MHz IF (0~20 MHz signal bandwidth) emulated nodes with flexible link type configuration. The maximal fading depth is 100 dB, the maximal Doppler shift is 2 MHz, and the maximal path delay can reach up to 2 s. It is a powerful tool in the spatial information networks design and research.

Key words: spatial information networks, dynamic network topology, analog IF signal processing, propagation characteristics, scalable architecture
