莫尔斯电报

The statistic of wavelet transform coefficient algorithm can solve the periodic noise , high - energy noise and some non - gauss noise simply and effectively ; bi - spectrum can acquire more information from the original signal than power - spectrum , detect more information except from range and restrain the gauss noise . short - time speech signal can be considered as stationary and with periodic non - gauss signal , so we can make use of bi - spectrum to obtain the speech character and separate the speech and noise and detect morse telegraph signal ; complex number spectrum variance algorithm is put forward based on the deeply observing speech data , it is a new algorithm , experiment show that it is simple , effective
统计算法在解决周期信号、高能噪声和高斯信号方面有独特之处,能简单有效提取以上噪声的特征;双谱能够提供比功率谱更多的有用信息,有效地检测信号幅度之外的其它信息,并能有效抑制高斯噪声,短时语音信号一般认为是平稳且有一定的周期性的非高斯信号,因而可以利用双谱来提取语音信号特性并实现信噪分离;复数谱方差算法是在对语音信号进行深入观察和分析的基础上而提出来的一种全新的语音特征提取方法,此方法简单而有效的提取了语音、噪声的特征以及检测莫尔斯信号,基于实验表明,该算法取得了很好的效果。
