一种适用于电气化铁路信息传输的主从结构自适应噪声对消器

An adaptive noise canceller with master slave structure for information transmission systems in the electrified railway

提出采用一种新型的主从结构的自适应噪声对消器 (MS- ANC) ,解决电气化铁路中的谐波干扰和高斯白噪声对消问题。计算机仿真实验表明 ,此噪声对消器能使输出信噪比得到较大的提高 (信噪比改善 15～ 40d B)

In this paper, we propose to use a novel adaptive noise canceller with master slave structure (MS ANC) to cancel those harmonic interference and Gaussian noise appeared in the electrified railway. By simulation, we can get the conclusion that this system can improve the signal to noise ratio (SNR) of the output greatly (enhance the SNR about 15~40 dB).
