Matlab codes for single carrier frequency division multiple access SC-FDMA simmulation. The codes may be useful for SC-FDMA

主要介绍GALQR的算法及应用，参考一下(Introduces GALQR algorithms and applications, refer to)

ODE function 求解一阶线性常微分方程(ODE function for solving first-order linear ordinary differential equations)

说明：  direct transform method for data

说明：  数据降维工具箱，包括一些典型算法，例如pca，lle，mds，lda等。(Data dimension reduction toolbox, including some typical algorithms, such as PCA, LLE, MDS, LDA, etc.)

余向阳博士Matlab教程的源代码。 包括：1.非线性方程的解法；2.线性方程的数值解法；3插值法；4.常微分方程的解法(Dr. Yu Xiangyang Tutorial Matlab source code. Include: 1. Non-linear equations 2. The numerical solution of linear equations 3 interpolation 4. The solution of ordinary differential equations)

根据过渡带宽及阻带衰减要求，选择窗函数的类型并估计窗口长度N（或阶数M=N-1），窗函数类型可根据最小阻带衰减As独立选择 (According to the transition bandwidth and stopband attenuation requirements, select the type of window function and estimate the window length N (or the order of M = N-1), type of window function according to the minimum stop-band attenuation can be independently selected As)

基于小波变换和OMP算法的稀疏表示,不仅包括适用于黑白图片的程序，也包括适用于彩色图片的程序。(the sparse representation basing on wavelet and omp,not only for the gray image,but also color image )

A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.

使用快速傅里叶变换fft实现带有高斯白噪声的频谱估计(Using fast Fourier transform fft achieve spectrum estimation with Gaussian white noise)
