模拟与数字信号的正交调制原理与实现

The principle and implementation of quadrature modulation of analog and digital signals

正交调制技术是软件无线电体系中的关键技术之一。本文在分析正交调制基本原理的基础上,介绍了模拟调制与数字调制的正交分解方法和基于AD9364平台的通用正交调制方案,为多模式调制设计提供借鉴。

Quadrature modulation technology is one of the key technologies in software radio system.This paper introduces the orthogonal decomposition method of analog and digital modulation and general quadrature modulation scheme based on AD9364 platform,on the basis of analyzing the basic principle of quadrature modulation,to provide reference for the design of multi-mode modulation.
