块自适应处理算法先有采样快拍数据计算采样协方差矩阵，再来计算自适应权矢量。典型的块自适应处理算法为采样矩阵求逆(SMI)算法。仿真了采样矩阵求逆法(SMI)的波束形成方向图旁瓣的高低受信号快拍数的影响。(Block adaptive processing algorithms prior sample snapshot data of the sampling covariance matrix, again computing adaptive weight vector. A typical block adaptive processing algorithms for the sample matrix inversion (SMI) algorithm. Simulation of the sampling matrix inversion method (SMI) beamforming pattern sidelobe level of the signal by the number of snapshots.)

dct precoded SLM method for PAPR reduction High Peak to Average Power Ratio (PAPR) is still a most important challenge in Orthogonal Frequency Division Multiplexing (OFDM) system. In this paper, we propose a Discrete Cosine Transform (DCT) precoding based SLM technique for PAPR reduction in OFDM systems. This technique is based on precoding the constellation symbols with DCT precoder after the multiplication of phase rotation factor and before the Inverse Fast Fourier Transform (IFFT) in SLM-OFDM System.

说明：  手写傅里叶反变换，通过矩阵变换实现的傅里叶逆变换，修改读入图像名就可以实现对应图像的傅里叶反变换，并与MATLAB内置函数进行比较(Inverse Fast Fourier Transform)

说明：  用 CC法计算延迟时间和潜入位数的matlab程序(CC method with delay time and the median into the matlab program)

说明：  通过matlab的强大的计算功能，生成由1024点构成的正弦波、三角波、锯齿波，同时在界面显示波形。(Through the calculation of the power of matlab functions to generate points from 1024 constitute the sine wave, triangle wave, sawtooth wave, at the same time show the waveform of the interface.)
