【摘要】 提出一种新的阈值函数,分析、实现传统的小波域固定阈值增强算法和基于TEO的小波域自适应阈值增强算法,并针对其部分不足,结合小波系数相关性的特性提出一种新的语音增强算法,实验结果证明该方法是可行的,而且增强效果比前两种方法也有所改进。更多还原

【Abstract】 The paper proposes a new threshold function,after programming of traditional wavelet threshold enhancement algorithm and the TEO enhancement algorithm,a new enhancement algorithms based on the correlation of the wavelet coefficients characteristics is proposed.Experiment results show that the method is feasible and effective,and the effectiveness of enhancement is better than two methods mentioned before.更多还原
