说明：  是matlab语言，对阶跃折射率分布均匀光纤（圆柱型光纤）模型中的光场分布进行了模拟。(Is the matlab language, a step refractive index distribution of the fiber (cylinder-type fiber) model of optical field distribution are simulated.)

实验结果表明该算法对非冲击噪声效果良好。 lx_main为主程序，NS_lxwz为噪声估计模块，lxG_wz为增益估计模块，noise_sound为测试用含噪语音。 算法原理参见本人的文章《一种引入延迟的语音增强算法》。(Experimental results show that the algorithm for non-impulsive noise effect is good. lx_main the main program, NS_lxwz for the noise estimation module, lxG_wz for the gain estimation module, noise_sound to test the noisy speech. Algorithm theory see my article " delay the introduction of a speech enhancement algorithm." )
