这是我编写的基于Matlab的QPSK调制解调的仿真程序，希望对大家有所帮助(This is what I prepared in Matlab based on the QPSK modulation and demodulation of the simulation program, and they hope to help everyone)

说明：  比较简洁的OFDM+QPSK的仿真,带AWGN和误码率统计(Simple comparison of the simulation of OFDM+ QPSK with AWGN and bit error rate statistics)

用于INSAR技术的matlab处理程序，包括形成干涉图、去平、滤波、相位解缠等步骤。(a processing basing on matlab which is used for the technology of INSAR.)

matlab建模工具箱及其应用 功能强大 收藏了很久了 和大家一起分享(Modeling and Its Application matlab toolbox powerful collection of a long time and the community together to share)

Example of using huge page memory in a user application using the mmap system call.

信号分析与处理，第一部分_序列的产生和序列的傅立叶变换，第二部分_序列的卷积，第三部分_FT时域卷积定理验证，(Signal processing analysis and application.)

信号子空间拟合，用matlab实现ssf算法，实现多维搜索，信号定位。(Signal subspace fitting algorithms to achieve ssf matlab, achieve multi-dimensional search, signal positioning.)

说明：  基于matlab简单图像处理系统中对图片的取反功能(Based on a simple matlab image processing system for the inversion of the image)

老外编的标准pso算法的matlab工具箱，该工具箱将PSO算法的核心部分封装起来，提供给用户的为算法的可调参数，用户只需要定义好自己需要优化的函数(计算最小值或者最大值)，并设置好函数自变量的取值范围、每步迭代允许的最大变化量(称为最大速度，Max_V)等，即可自行优化。(Part of the standard of foreigners pso algorithm matlab toolbox, the toolbox will be the core of the PSO algorithm package together to provide to the user adjustable parameters for the algorithm, users only need to define their own needs better optimization function (calculation of minimum or maximum value), and set a good function, since the range of variables, each iteration step the maximum allowable variation (known as the maximum speed, Max_V) and so on, can be self-optimizing.)
