射频直接带通采样软件无线电结构分析及其应用

Study of RF Direct Bandpass Sampling Structure of Software Radio & its Use

软件无线电技术经过近十年的发展已取得了很大进步,根据采样原理,它有三种基本的结构,这里主要是对射频直接带通采样软件无线电结构进行了详细分析,并与其他两种结构进行了比较,找出制约其发展的主要因素,就目前应用情况及未来发展发表了见解。

Software radio technology has made great progress since 1992. It has three fundamental structures based on Nyquist sampling theory. In this article, the author makes a detailed analysis of the RE direct bandpass sampling structure of software radio and compares it with two other structures, thus finding out the restrictions on its development. Also presented in this article are the authors comments on its present application and future development.
