摘要
自适应噪声抵消系统是基于自适应滤波原理的一种扩展,它能从被噪声干扰的环境中检测和提取有用信号,抑制或衰减噪声干扰,提高信号传递和接收的信噪比质量。研究常用噪声消除算法,并仿真验证系统设计和所选自适应算法的可行性,最后应用DSP技术设计一个自适应噪声抵消系统,使其能消除含噪语音信号中的背景噪声,达到提高语音信号质量的目的。
The adaptive noise canceling system develops from the adaptive filtering system. It can improve the quality of signal by picking up and detecting the useful signal or canceling noise in the environment that is interfered by noise, The algorithms of noise canceling were introduced. The results of background noise from noisy speech signal, and reach to the purpose of improves the quality of speech signal.
