摘要
文章论述了软件无线电的各种结构,对其各种结构的优缺点进行了分析,然后结合实际电台研制工作,给出一种基于射频数字化的短波软件无线电台方案。该方案采用了射频低通采样数字化结构和动态加载配置技术,能够显著减少传统短波电台中过多的模拟处理环节,实现波形的动态加载,提高短波电台的整机性能。实际电台测试结果验证了该方案的可行性。
Based on a detailed analysis of different structures of software-defined radio, a novel HF software radio scheme using RF direct digitalization and dynamic configuration techniques is presented, which can greatly reduce the traditional analog processing stages, load application waveforms dynamically, and effectively improve the radio performance. The validity is verified by radio field test.
