matlab lte sc fdma ofdma channel estimation

本设计研究了纠错码及循环冗余校验码的原理，以及利用MATLAB对其进行了编程和编译仿真，实现了CRC循环冗余校验码的编码及校验，在接收端收到通过校验的码.(This design research the error correcting code and cyclic redundancy check code principle, and the use of the MATLAB programming and compile the simulation, realized the CRC cyclic redundancy check code coding and check, at the receiving end received through the check code.)

利用小波变换多尺度分析的特性,在小波域的各个尺度上选取不同的阈值对基本的频域谱减法进行改进,并且根据清浊音各自不同的特点,在去噪过程中加以分离,保留了语音中的清音成分,使语音更加饱满。(The use of multi-scale wavelet analysis of the characteristics of the individual in the wavelet domain scale threshold select a different frequency domain of the basic spectral subtraction to improve and, in accordance with their respective Qingzhuo sound different characteristics, in the denoising process be separated from the retained voice of the voiceless in the composition, more full of voice.)

matlab编写的随机森林算法，别人编写的，分享一下(Random Forest algorithm matlab prepared, written by someone else, share)

说明：  运用matlab进行模糊聚类分析步骤如下：建立数据矩阵；数据标准化；建立模糊相似矩阵；改造相似关系为等价关系；确定分类数(The steps of using MATLAB to carry out fuzzy clustering analysis are as follows: establishing data matrix; standardizing data; establishing fuzzy similarity matrix; transforming similarity relation into equivalent relation; determining classification number.)

高斯法求解方程，在matlab中建立，求解方程并显示运算时间结果，用于对高斯法有一个更直观的认识。(Gauss method for solving equations, established in matlab, solving equations and displays the computation time results for the Gaussian method has a more intuitive understanding.)

輸入點位於WGS84之大地經、緯度，可於命令窗顯示此點之卯酉圈曲率半徑N、子午圈曲率半徑M及平均曲率半徑R及此點之空間直角坐標X、Y及Z。(Input point is located in the WGS84 geodetic latitude and longitude can be displayed in the command window of the prime vertical radius of curvature point N, M meridian radius of curvature and the average radius of curvature R and the point of the space rectangular coordinates X, Y and Z.)

基于粒子群算法的函数求最大值的matlab程序，自己照书编写的(PSO algorithm based on the function of matlab procedures for the maximum, according to the book written their own)

It will make negative of input image

说明：  用matlab实现的稀疏字典学习算法，可以用于图像去噪、图像分类、图像识别等(Sparse dictionary learning algorithm implemented by Matlab can be used for image denoising, image classification, image recognition and so on.)
