Adaptive Filtering Primer with MATLAB - Poularikas and Ramadan

1. 基于simulink搭建一个QPSK发送链路，QPSK调制信号经过了瑞利衰落信道，观察信号经过衰落前后的星座图，观察信道特性。仿真参数：信源比特速率为500kbps，多径相对时延为[0 4e-06 8e-06 1.2e-05]秒，相对平均功率为[0 -3 -6 -9]dB，最大多普勒频移为200Hz。(1. Based on simulink structures, QPSK sent a link, the Rayleigh fading channel after the QPSK modulation signal, were observed before and after signal after the decline of constellation diagram, observation channel characteristic. Simulation parameters: the source is 500 KBPS bit rate, relative multipath time delay of [0 8 e 4 e- 06-06 e-05] 1.2 seconds, the relative average power is [0-3-6-9] dB, most of the doppler frequency shift is 200 hz.)

书中全面系统地介绍了优化方法的基础理论和优化工具箱v2.2函数的功能、语法和工程实际应用。 (The book introduces a comprehensive and systematic optimization approach is based on theory and optimization toolbox v2.2 of functionality, syntax and engineering applications.)

快速解方程组，用MATLAB解方程组，快捷！(Rapid solution equations, solution of equations with MATLAB, fast!)

stprtool的使用文档，非常好的模式识别工具包，里面有关于核的以及贝叶斯的相关程序，以及PCA，EM，SVM等方法。 (stprtool the use of the document, very good pattern recognition tool kit, which has nuclear as well as Bayes procedures, as well as PCA, EM, SVM and other methods.)

论文 Least Squares Loss for Multi-class (task) Learning via the sparse group Lasso penalty 的算法源代码，是sparse+l1+lq,1的稀疏属性选择算法。( Least Squares Loss for Multi-class (task) Learning via the sparse group Lasso penalty Problem min 1/2 || A x- y||^2+ lambda_1* |x|_1+ lambda_2*|x|_{q,1} q=2, infty)

说明：  九节点的潮流计算matlab程序，可以用来进行电力系统的潮流计算。(power system flow calculation)

本源码将横向自适应滤波器和格型自适应滤波器的LMS算法综合在一起,对起权系数跟踪性能可以做较好的比较(The source transverse adaptive filter and adaptive lattice filter LMS algorithm combined starting weight coefficient tracking performance can do a better comparison)
