| 摘 要： | 针对一个自适应滤波器不能解决多噪声信号的问题,提出了自适应滤波器的组合设计思想。在线性组合条件及LMS算法下,分析多噪声抵消原理,并进行多噪声语音信号的Matlab仿真实验,可以得到清晰的语音信号。结果表明,自适应滤波器的组合设计可以有效抵消多种干扰信号。

| Abstract: | It presents the idea of combination design basing on the fact that the adaptive filters can't achieve the requirements to offset multi noises.According to the linear combination and algorithm of LMS,it also analyzes the principle of multi noise cancellation.The Matlab simulation on multi noises gets clear voice signal.The result shows the combination design of adaptive filters can effectively offset many types of interference signals. |
