一种在DSP中产生高性能粉红噪声的方法

摘要

粉红噪声是电子、信号处理乃至声学领域常用的随机信号。针对于以PC机为代表的串行处理设备上生成的粉红噪声效果较差的问题，该文提出了一种在DSP中采用改进的混合同余法生成平稳白噪声并利用参数模型法来生成粉红噪声的方法。实验表明：在DSP中得到了性能良好的粉红噪声。%Pink noise is often used in electronics, signal processing, and acoustic field. In represented by PC serial processing equipment which cannot generate the ideal pink noise, so this paper presents the method which with the improved mixed congru-ence method to generate a steady white noise and the method which through a parameter model to generate pink noise in DSP. Eventually,I get the good performance of pink noise.
