基于MATLAB的自适应噪声抵消器设计及应用研究

Design and Application Research of Adaptive Noise Canceller Based on MATLAB Software

自适应噪声抵消技术在信号处理中得到越来越广泛的应用。在讨论自适应噪声抵消器原理的基础上,进行了自适应噪声抵消器的设计并借以MATLAB予以实现。最后,以胎儿心电图信号检测为例,分析了自适应噪声抵消技术的应用,通过计算机模拟仿真,给出了仿真结果,使待检测信号得到了较好的噪声去除。

Adaptive noise cancellation technology is playing very important role in signal processing. After discussing the principle of adaptive noise canceller, some design of adaptive noise canceller is carried out and some corresponding design results are got. Finally, the application of adaptive noise cancellation technology to the fetal electrocardiograph signal detection is analyzed, and then some good simulation results are given.
