信噪比改进技术的新发展

A Recent Advance in Improving Signal to Noise Ratio

概述了改进信噪比在信号分析与处理领域的重要性。针对常用改进信噪比方法的不足之处 ,介绍了小波去噪方法的基本原理。并在基于最小二乘法的降噪方法的基础上 ,提出了一种通过滤波的改进的最小二乘法。还介绍了文中所提出的方法在通过计算机进行运算处理时的步骤。最后 ,通过仿真数据说明了该方法的实用性和有效性。

This paper summarized the importance of improving signal to noise ratio in the area of signal processing. In view of the deficiencies in excisting methods for improving signal to noise ratio, an improved pre filtering method based on the least squares is proposed in the paper. Computer simulation results show that the proposed method is practical and efficient.
