【摘要】 文中分析了声信号中随机噪声去除的可能性，讨论在时域上滤除随机噪声的算法。在分析和比较了固定滤波、自适应滤波等在时域上滤除噪声方法的基础上，提供使用最小均方自适应滤波的方法，研究了最佳滤波因子的获得和滤波参数的选择。用很小的运算量取得了较好的效果。更多还原

【Abstract】 The possibility of wiping random noise off the sound signal andalgorithm of filter noise in time domain is given. After comparing the fixed filterwith adaptive filter at the way of filtering noise in time domain, LMS adaptive filter methodis given. The getting way of optimum filtering factor and choice of filtering parameters are studied. The good result is obtained by the least calculation quantity.更多还原
