电磁波Yee Cell FDTD交错网格场量位置示意图 画图程序 TE 波TM波 TEM波都有(Yee Cell FDTD electromagnetic field quantity staggered grid position diagram drawing program TE, TM waves are TEM wave)

数字信号处理软件设计，能够产生常见的数字信号如：正弦波 三角波 随机信号 以及高斯噪声，并对其进行频谱分析 同时也包括FIR IIR滤波器设计，并对产生的数字信号进行滤波(software design of digital signal processing that can generate many signals ,analysize their frequency Spectrum and design filter(FIR、IIR)to filter.)

In this letter, we derive a minimum mean squared error (MMSE) optimal estimator for clean speech spectral am-plitudes, which we apply in single channel speech enhancement. As opposed to state-of-the-art estimators, theoptimal estimator is derived for a given clean speech spectral phase. We show that the phase contains additional information that can be exploited to distinguish outliers in the noise from the target signal.
