I/Q双通道正交误差测量方法的研究

Research on Methods for Measuring Quadrature Error of I/Q Bichannel

本文在计算机模拟的基础上构造了一个对I/Q双通道正交误差的测量方案 ,用Hibble变换方法与椭圆方法相结合可使误差小于 0 .5°.

A method combing Hilbert transform and Eillptical algorithm to measure the quadrature error of I/Q bichancel is presented in this paper.The experimental results show that the new method is more accurate.
