一个关于BPSK误码率仿真的程序，内容只包括误码率仿真部分！(One on BPSK BER simulation procedures, including the signal generated by adding Gaussian white noise, and bit error rate!)

In statistics, an expectation-maximization (EM) algorithm is a method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. EM is an iterative method which alternates between performing an expectation (E) step, which computes the expectation of the log-likelihood evaluated using the current estimate for the latent variables, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.

在平滑信号中加入高斯分布的白噪声，然后用db4小波函数进行多尺度分解，滤除白噪声，将滤波前后的图进行对比(Add the Gaussian distribution of the white noise in the smoothed signal, and then multi-scale decomposition db4 wavelet function, the filtered white noise, comparing before and after filtering)

硕士论文：粘弹性介质地震波数值模拟。 震波在实际地层介质中传播与在理想的完全弹性介质中传播有许多不同之处，地层的粘滞性会损耗地震波能量，使其振幅衰减并且视频率逐渐降低。地震波的这种能量 衰减和频散，使得不能直接从地震数据上得到准确的地下信息和分辨率更高的图像。实 际的地层更接近于粘弹性介质，本论文主要探讨和研究了粘弹性介质中地震波传播的数 值模拟方法及其衰减规律。 (Thesis: viscoelastic medium seismic wave numerical simulation. The shock wave propagation in the formation medium and ideal perfectly elastic medium spread there are many differences, the viscosity of the strata will loss seismic energy, so that the amplitude attenuation and video rate gradually reduce. This energy of the seismic wave attenuation and dispersion makes accurate subsurface information and higher resolution images can not be obtained directly from the seismic data. Actual formation closer viscoelastic medium, this thesis is to explore and study the numerical simulation of seismic wave propagation in viscoelastic media and its decay law.)

关于电磁波散射的时域有限差分法计算程序 很好的(a code about finite difference time domain method for electromagnetic waves scattering)

用于灰色关联系数和灰色关联度的计算，其中进行了初值化和归一化处理。(Correlation coefficient for the gray and gray correlation calculation, which carried out the initial value of and normalized.)

我们设计和实验证明 布拉格光栅波分复用器 三波长的平面光波电路复用 公交车站台。1310和1550 nm的光，被设计成 由一个半周期通过定向耦合器分离后 和一个完整的周期耦合作用与0.07和0.19分贝的损失， 分别。1492 nm的光反射回来的布拉格 光栅对定向耦合器及其制作少损失 超过2分贝。我们也介绍和讨论新概念 集成光学三工收发器，使用此过滤器。 (We designed and experimentally demonstrated a Bragg grating-assisted wavelength-division-multiplexing filter for the three-wavelength multiplexing on a planar-lightwave-circuit platform. The 1310- and 1550-nm lights were designed to be separated after passing the directional coupler by a half-cycle and a full-cycle coupling actions with losses of 0.07 and 0.19 dB, respectively. The 1492-nm light was reflected back by a Bragg grating fabricated on the directional coupler and its loss was less than 2.0 dB. We also introduced and discussed the new concept of an integrated optical triplexer transceiver using this filter.)
