channel estimation for ofdm using legendre polynomials

matlab数字图像处理 彩色图像处理部分 含代码和结果显示(matlab image processing color image processing section Containing the code and the results show)

说明：  经典常规波束形成 包含几种方法的对比(Classic conventional beamforming with comparison of several methods)

压缩感知的很简单的入门小例子，基矩阵为正弦基，能很好地重构出稀疏信号(A simple example for the introduction of CS theory, the basis matrix is sinosoidal matrix, which can fully reconstruct the sparse signal.)

this code uses inverse linear interpolation method to solve non linear system to equations.

这是一个有用的程序，我相信对你们也有用的(This is a useful program, I believe you also a useful)

future work for hop by hop

代码实现了二阶AR模型的最优权值递推，使用了LMS和RLS两种方法，对二者性能进行了比较，分别进行了单次和100次平均进行性能观察，并且仿真了不同步长因子对LMS算法的影响以及不同lamda值对RLS算法的影响。文档包含了模型的详细介绍以及2种方法的理论仿真和结果分析。代码以附在之后。(Code to achieve the optimum weights recursive second order AR model, the use of LMS and RLS are two methods were compared for the two properties, were observed and 100 times the average per-performance and simulated sync Effect of a growth factor RLS algorithm impact on LMS algorithm and different lamda value. Document contains the results of theoretical simulation and detailed description of the model and two methods of analysis. Code annexed.)
