- 提出一种有效的语音增强算法,该算法使用重叠相加FF-r滤波器进行谱幅度估计,给出噪声估计的两个均值参数,此参数适用于任何噪声.而且进行噪声估计无需检测语音间隙,无需VAD的运算过程,克服了单信道噪声 压缩算法的缺点.-An effective speech enhancement algorithm using the overlap-add FF-r filter in spectral amplitude estimation, given the noise mean estimate

- 基于最大重叠离散小波谱的定义, 本文提出了一种确定分形信号局部奇异性指数的算法, 构造了一种 类似于奇异性谱的直方图, 并用之来描述信号奇异性的全局统计分布. 算法的有效性通过数字试验及在真实心率数据 中的应用得到了验证.-Based on the definition of wavelet spectrum of the maximal overlap discrete wavelet transform, we propose a novel algorithm for dete
