摘要

使用Hadamard变换方法的离子迁移谱仪可以提高提高离子占空比（DC）

从而改善仪器的信噪比。本文基于离子迁移谱仪的硬件平台

对离子谱的处理进行了Hadamard变换实验。实验结果表明

与传统的处理方法相比Hadamard变换方法对离子迁移谱仪信噪比的提高和改善是非常有效的。

Abstract

Hadamard transform can improve the SNR by increasing the ion duty cycle in IMS.In this paper

the ion spectral signals were processed by Hadamard transform based on the IMS detector hardware platform.The results showed that Hadamard transform can greatly improve the SNR of the IMS detector in contrast with traditional method.
