高斯噪声实时产生算法及在ADSP-TS201S上的实现

Implementation of Real-time Algorithm of Gaussian Noise on ADSP-TS201S

讨论了几种产生(0,1)均匀分布伪随机数的方法,以及几种用其进一步产生服从正态分布随机数的方法。并根据实时性要求,选择其中一种产生数据速度较快的算法,在ADSP-TS201S浮点DSP上实现,实时产生两路相互独立的高斯白噪声数据。

This paper introduces several methods to generate pseudo random numbers obeying the （0, 1） uniform distribution, as well as several methods to generate normal distribution random numbers. Based on the real-time require- ment, one faster generating algorithm is selected to be implemented on floating-point DSP ADSP-TS201S, which generates two-channel independent real-time white gauss noise data.
