车辆导航系统DSP算法精度和显示技术研究

Research into DSP Algorithm Precision and Digital Signal Technology in Vehicle Navigation System

文章主要研究车辆导航定位系统在工程实现过程中的两个技术问题:数字信号处理器DSP数据有效位受限制的问题和跑车路线显示程序的设计过程中遇到的问题。试验结果表明,文中所提出的解决方案有效的解决了上述问题,使车辆导航系统达到了设计的性能。

In this article, we put forward two problems:(1) valid bits of DSP float data type is finite, just seven valid bits; (2)how to set and renew coordinate axes,and how to store and read vehicle position into in the degign of route digital signal program. The experiment results show that our method works well.
