这是基于simulink的ofdm仿真程序， 毕业设计中用的 希望对大家有用(this is a OFDM simulation program based on simulink. and this is also my paper program. i hope that it is benefical to you！it can be used by matlab 2009)

DVB-T，DTMB简化的信道仿真程序。设置了三种保护间隔：循环前缀、零添加、伪随机添加。用于研究不同保护间隔下的SNR特性，附带一个不同保护间隔下的频谱显示，可看出三种保护间隔对OFDM频谱陡峭程度的影响。(DVB-T，DTMB channel simulation and spectrum display.)

Thats Phase shift key program wich is very good for sudents Begginers can educate very well because cod is easy to be understod from everyone

本文件是关于阵列天线方面的方向图计算程序(This document is on aspects of array antenna pattern calculation program)

calculates the bentley sweep algorithm between two trapezoidal membership functions

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.)

说明：  基于遗传算法的OFDM自适应资源分配算法MATLAB源码 OFDM自适应资源分配问题（载波、功率等），是一个既含有离散决策变量，又含有连续决策变量的非线性优化模型，且含有较为复杂的非线性约束，因此适合采用智能优化算法进行求解。 (Adaptive genetic algorithm-based resource allocation algorithm for OFDM OFDM MATLAB source adaptive resource allocation problem (carrier, power, etc.), is a decision with both a discrete variable, but also with continuous decision variables of the nonlinear optimization model, and contains more complex non-linear constraints, so smart optimization algorithm for solving.)

针对稀疏圆阵的波达方向估计问题，提出了解相干求根MUSIC算法（Sparse UCA Decorrelation Root-MUSIC，SDR）。通过改进传统的波束变换方法，进行相位校正，并在波束域进行误差补偿，得到具有共轭对称结构的波束域导向矢量。在波束域进行前后向平均处理和使用求根MUSIC算法(In order to solve the direction of arrival estimation of sparse circular arrays, a new understanding of the Sparse UCA Decorrelation Root-MUSIC (SDR) algorithm is proposed. By improving the traditional beam transform method, phase correction, and error compensation in the beam domain, a beam-domain steering vector with a conjugate symmetry structure is obtained. Averaging forward and backward in the beam domain and using the root-finding MUSIC algorithm)
