NC-OFDM系统的导频设计改进方法性能分析(Pilot design method of NC- OFDM system to improve performance analysis)

2维均匀圆阵下 MUSIC DOA（波达方向）估计，通过谱峰搜索得到信源的俯仰角和方位角。(Under the two-dimensional uniform circular array MUSIC DOA (DOA) estimates obtained by the source spectral peak searching elevation and azimuth.)

变步长的最小均方算法，步长可变，性能好，收敛速度快。(Variable step least mean square algorithm,have fast convergence rate.)

这是一本关于子空间辨识方法的好书！！里面有详细介绍。(This is a good book about subspace identification method! ! More details inside.)

自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)
