基于SDR-4902平台的波形部署算法设计与实现

摘要

In this paper,the automatic deployment mechanism,in which waveforms in the system start-up and running stages are adopted in the hardware platform,is presented based on the wide frequency range and high bandwidth general soft-ware defined radio platform SDR-4902. Firstly,an analysis on the factors which affect the decision-making mostly through the whole deployment process between the waveform and hardware platform in practical application environment is done,and a sys-tem model of the waveform deployment is presented. Secondly,a waveform algorithm based on the dynamic programming princi-ple is proposed,and an implementation pseudocode is shown. Finally,to verify the proposed method,parameters extraction from the SDR-4902 and a demonstration waveform and deployment result is presented,and the result indicates that the proposed method is reasonable and effective.%基于宽频段、高带宽的通用软件无线电平台SDR-4902，实现了系统启动或运行阶段波形应用到硬件平台的自动部署。首先，充分地分析了影响波形应用到硬件平台部署决策的各种因素，进而构建了统一的系统模型；接着，提出了基于动态规划原理的波形部署算法，并给出算法伪代码；最后，为了对本方法进行验证，提取SDR-4902平台和一个示例波形的平台和应用参数以及利用部署算法获得部署结果，结果表明该方法是合理且有效的。
