二次拟合

这是一个OFDM系统的信道估计仿真MATLAB，分析了基于训练序列的估计方法(This is an OFDM system channel estimation simulation MATLAB, analysis of the estimation method based on training sequence)

matlab环境下模拟单服务台排队，通过程序设置到到银行排队办业务的人的人数及时间间隔，计算平均每个人需要等待的时间。(set the number of the queue，and the time between each comer ,it will calculate the average waiting time of each person)

用于生成3D显示所需的针孔阵列，每个针孔为正方形。(for 3D displays.)

code in matlab for detection

This program code is for compressing a file or image using Huffman coding without any built-in functions.

应用傅里叶变换DFT，分析各种离散信号x(k)的频谱。离散周期信号可以展开成傅里叶级数，所以离散周期信号的频谱 是一个周期的周期性离散频谱，各谱线之间的间隔为 ，而且存在着谐波的关系。 (DFT application of the Fourier transform, analyze discrete signal x (k) of the spectrum. Discrete signal cycle can begin as Fourier series, the discrete signal spectrum is a cyclical cycle of discrete spectrum, the line between the interval, but there is a harmonic relationship.)

图像中值滤波，利用中值滤波和低通滤波进行比较，分析PSNR，得出性能差别(image filtering, using median filter and a low-pass filter, PSNR analysis, the performance differences come)

肠型胃癌的基因表达谱数据。已经处理好。空缺值用均值代替。 第一行是肠型胃癌基因表达谱数据中样本的类别

采用非局部均值滤波（NLM filter）对图像进行去噪，能取得很好的效果。(Using non-local means filter (NLM filter) for image de-noising, can achieve good results.)
