Design and Accomplishment of the Eight-channel IF Digital Modulation System Based on Software Radio Technology

介绍一种采用软件无线电技术用于基站的多信道中频数字化调制系统的设计,提出了该系统总体设计方案,说明了软件无线电中的无线电功能的模块划分,给出了系统关键部分的硬件实现方法和软件流程设计以及工程实现中应考虑的几个主要问题。

This paper introduces the design of the multi-channel IF digital modulation system applied in base station, which is based on the software radio technology, and offers an overall design scheme of this system. It explains the radio module partition in the aspects of functions and the existing status of data flow in the system and lists some of the system's key hardware together with the software design flowchart. It concludes with the main considerations in the design of this system.
