能实现人脸的简单匹配算法，本人亲自测试，还行吧(To achieve a simple matching algorithm, face, OK.)

该程序是关于参数化功率谱估计，这些源程序是经过验证的，很好使用(The program is about the parametric power spectrum estimation, the source is a proven, well used)

说明：  由4个.m文件组成，用于16QAM和64QAM调制的软信息的提取(By 4. M files for 16QAM and 64QAM modulation of the soft information extraction)

matlab格式的布谷鸟搜索算法（cuckoo search）程序(matlab format Cuckoo search (cuckoo search) program)

mvdr算法是最小方差无畸变响应波束形成器，它的原理来自是使非期望波达方向的任何干扰贡献的功率最小，但又能保持观测方向的信号功率不变。(mvdr algorithm is the minimum variance beamformer response distortion, its principle is that any interference from the direction of arrival of the undesired contributions to a minimum power, but the power of the signal while maintaining constant observation direction.)

改程序实现QPSK系统的性能仿真，仿真与理论相符，供大家参考。(QPSK System Simulation, Pe evaluation)

说明：  遗传算法实现50维函数优化，代码简单易懂，适合初学者。(Genetic algorithm of 50-dimensional function optimization, code easy-to-read, suitable for beginners.)

计算图想的傅里叶变换并显示其频谱，本设计中显示了四种图像的频谱，供大家学习和参考，比较每一种频谱的不同！(Map to calculate and display the Fourier transform of the spectrum, the design spectrum shows four images for all to study and reference, compare the different spectrum of each!)

说明：  mcmc的matlab实现，可用于参数估计(mcmc code by MATLAB,it can use to estimate the parameters)

蚁群算法的源代码，蚁群算法又称蚂蚁算法，是一种用来在图中寻找优化路径的机率型算法。(Ant colony algorithm source code, algorithm, also known as ant colony algorithm is a method used to find the optimal path in the graph the probability-based algorithm.)
