Abstract

The research and application of ultrashort wave are more and more wide ultrashort wave communication has become an indispensable communication way in the field of modern communication, especially in military communication. Based on the needs of ultrashort wave wireless communications technology development, this paper gives theoretical analysis and simulation verification on channel characteristics of ultrashort wave, and gives the VHF channel simulator implementation scheme on the software defined radio platform. This paper views the background and research significance of the ultrashort wave channel transmission characteristics and has research on channel transmission characteristics such as the multipath transmission delay, Doppler shift frequency expansion, large-scale fading. Through analysis and comparison of the channel model, this paper chooses the irregular terrestrial transmission channel model weighted small-scale fading model as the primary model. This project gives the theoretical simulation based on the actual needs of the project.

基于SDR平台的甚高频信道模拟器设计

超短波的研究和应用越来越广泛，超短波通信已成为现代通信领域，特别是军事通信中不可缺少的一种通信方式。根据超短波无线通信技术发展的需要，对超短波信道特性进行了理论分析和仿真验证，给出了在软件无线电平台上的甚高频信道模拟器实现方案。本文从超短波信道传输特性的研究背景和意义出发，对超短波信道传输特性如多径传输延迟、多普勒频移扩展、大规模衰落等进行了研究。通过对信道模型的分析和比较，本文选择不规则地面传输信道模型加权小尺度衰落模型作为主要模型。本课题根据项目的实际需要进行了理论仿真。
