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." )

仿真研究2PAM，4PAM眼图特性； 分别加入高斯白噪声，码间串扰，研究它们对眼图的影响； 改变接收滤波器的滚降系数，研究它对眼图的影响； 研究不同波特率对眼图的影响。 (Simulation studies 2PAM, 4PAM eye diagram characteristics were added white Gaussian noise, inter-symbol interference, influence their study eye chart changing the receive filter roll-off factor, the study of its effects on the eye research on different baud rate eye effects.)
