基于FPGA的高精度高斯白噪声产生方法

Method to Generate High-Precise Gaussian White Noise Based on FPGA

提出一种基于非均匀量化思想的高精度高斯白噪声产生方法.该方法在利用均匀分布与高斯分布之间的映射关系产生高斯白噪声时,通过将映射曲线分区化,不同分区的均匀噪声的量化精度不同,可产生高精度高斯白噪声.实测数据表明,该方法在满足噪声精度要求的同时极大地减少了硬件资源占用.

In this paper,a method to generate high-precision Gaussian white noise is proposed,which takes advantage of the mapping relationship between uniform distribution and Gaussian distribution.The highlight of this method is to increase the accuracy of the generated white Gaussian noise waveform by dividing the mapping curve into different partitions with unequal quantized precision.Experimental results have demonstrated that the proposed method can meet the noise precision requirement and reduce the FPGA resource consumption at the same time.
