摘要

提出了采用高阶累积量作为信号处理手段来抑制标准接收机的噪声效应。本文分析了差分全球定位系统(DGPS)接收机的噪声、接收机信道间偏转偏移、多距离误差等误差。该算法采用累积量切片的方法，使结果简单、准确。高阶累积量抑制高斯噪声的影响，提高了接收机的信噪比，提高了接收机的导航和车辆定位精度。

Research of signal processing method about vehicle positioning

It was proposed that using high-order cumulants as signal processing means restrains the noise effects of a standard receiver. The paper analyses the errors of a differential Global Positioning System (DGPS) receiver such as receiver noise, deflective shift between channels about receivers, multi-distances error etc. The algorithm adopts cumulants slices means to make the result simple and accurate. High order cumulants may restrain the effects of Gaussian noise, so the signal to noise ratio (SNR) about the receiver was improved and the precision of the GPS receiver was enhanced for navigation and vehicle positioning.
