Adaptive-Equalization

基于matlab的扩频通信设计，walsh码扩频，Bpsk调制(Matlab-based spread spectrum communication design, walsh code spread spectrum, Bpsk modulation)

In This Matlab Code we Use RLS Method To identify Any System Transfer Function, RLS is based of Recursive Least Squre Algorithm is very important method in System Identification.

基本模拟调制及其功率谱密度函数，有图的仿真结果，可以比较直观的进行理解(The basic analog modulation and power spectrum density function, a simulation results, can be more intuitive to understand)

说明：  KPCA的提出者亲自写的程序。是一份很值得收藏的经典代码。(KPCA the author himself procedures. It is a very worthwhile collection of classic code.)

小波分析以及消噪程序，很实用。希望对大家有帮助(wavelet anaysis and denoising program,very useful to everyone who wang to know about this.)

计算成组滑动的滑窗检测器的最佳门限已知: 击中数N = 128, 组宽n = 8，PF = 10¡ 6，PD = 90 假设以下条件: (a) 信号不起伏 (b) 忽略天线波束调制 1 (c) 计算PD时忽略目标区以外噪声的影响 组门限(第二门限)为K=8 滑窗的门限(第三门限)为L=16 (滑窗中包含的组数为16) 求解: 最佳的KOPT 和LOPT，对这题做了具体仿真实现。需要的朋友，一定知道很有用。(Optimal threshold calculated as group slidable window detector is known: hit number N = 128, the group width n = 8, PF = 106, PD = 90 assuming the following conditions: (a) signal is not undulation ( b) ignore the antenna beam modulation 1 (c) the calculation of PD ignored outside the target area noise of impact group door limit (the second door limit) for K = 8 sliding window of the door limit (third door limit) for L = 16 (sliding window contains group 16) to solve: the best of the KOPT the LOPT, these questions do specific simulation to achieve. A friend in need, we must know to be useful.)

极力推荐，PKU-Matlab课程的学习的PPT，很适合初学者。(Highly recommended, PKU-Matlab courses of study on the PPT, it is suitable for beginners.)

matlab中的pn码仿真 PN码的仿真实验 pn码在通信系统中占据了重要的位置，在即将到来的3G通信中比较重要(the pn Matlab simulation code PN code simulation pn code in communications systems occupy an important location in the upcoming three G communications more important)

数学问题的优化matlab算法实现，线性优化等问题(Matlab optimization mathematical problem algorithm, linear optimization problems)

信号被窗函数截断，并做频谱分析，比较汉宁窗、三角窗等的特点(Window function signal is cut off, and do spectral analysis, comparing Hanning, triangular windows and other characteristics)
