摘要
运用噪声对消法的基本原理 ,通过小波变换对染有噪声的语音信号进行了消噪处理 。
Filtering noise is one of the key techniques in signal processing. It is a effective method to reduce the noise in signal by wavelet multi scale decomposition. This text use noise offset the basic principles of law, utilizing wavelet transform, and make certain result.
