说明: 这里介绍了一种基于自适应滤波的噪声抵消法,采用归一化最小均方误差算法,采集实际噪声环境下各种不同信噪比的带噪语音样本进行降噪处理,实验结果表明,处理后信号的信噪比得到了较大程度的提高,大大改善了听音效果,具有很高的可懂度,且语音自然度好,没有失真;并与谱减法进行了比较,自适应噪声抵消法的降噪幅度比谱减法有一定提高,在听音效果上,用自适应噪声抵消法处理后的语音在清晰度,自然度方面优于谱减法。(Here a novel adaptive noise cancellation method using normalized least mean square algorithm, collecting a variety of actual noise environment, the SNR of noisy speech samples for noise reduction, experimental results show that treatment After the signal to noise ratio was greater improvement in the level, greatly improved the listening results, with high intelligibility and naturalness of speech is good, no distortion and were compared with the spectral subtraction, adaptive noise cancellation law than the spectral subtraction noise reduction rate of a certain improvement in the listening results, and with the adaptive noise cancellation method in the treatment of voice clarity, naturalness is better than spectral subtraction.)

该程序(基于matlab)为小波变换在数据压缩方面的应用。原理:数据可分为高频部分和低频部分,高频部分反映了细节,而低频部分则反映概貌,故压缩部分应为高频部分。数据经此程序变换后将压缩为原来的一半。(This program (based on matlab) for the wavelet transform applications in data compression. Principle: Data can be divided into high-frequency part and low frequency, high frequency part of the reflection of the details, partly reflecting the profile of low frequency, it should be for the high frequency part of the compression part. Data will be compressed by this program change to the original half.)
