摘要
美军联合战术无线电系统(JTRS)宽带组网波形(WNW),是一种新型的战术无线通信协议标准,从对宽带网络波形WNW的功能描述需求和场景思路出发,进行了仿真建模,主要从调制方式和信道编码等物理层技术上进行了波形设计,通过OFDM和SCFDE实现的关键模块构建了两种调制方式的基带信号传输系统,并对仿真结果进行了分析和性能对比,结合军用战术电台的软件无线电实现给出了相应的结论;也对军用战术电台JTRS WNW适用于Ad-hoc多跳自组网的USAP统一时隙分配协议进行了原理分析和方案实现的评价。
JTRS WNW is a new tactical wireless communication protocol standard. This paper describes simulation modeling of WNW according to its function description requirements and scenarios and provides wave design in terms of PHY technology including MCS and channel coding. In this paper, baseband signal transmission systems are built under two kinds of modulation modes with key modules implemented by OFDM and SCFDE, and simulation results are also analyzed and compared in performance. At last, the conclusion is given combining with software defined radio implementation of military tactical radio, as well as principle analysis and scheme evaluation on USAP of JTRS WNW applied to Ad - hoc multi - hop self - organizing network.
