用Adaboost+PCA进行特定的目标识别(Specific target recognition by adaboost&PCA)

现代通信系统(MATLAB版)(第二版)刘树棠译 本书系Brooks/Cole出版公司（Thomson Learning出版集团的下属子公司）2000年推出的BookWare系列丛书（BookWare Companion SeriseTM）之一种。该书提供了利用MATLAB的普及型学生版本在计算机上解决“现代通信系统”这门课程中涉及的几乎所有方面的问题的分析思路、方法、MATLAB脚本文件和处理结果的范例以及供学生自主学习研讨的习题。全书内容分为9章，分别是：信号与线性系统；随机过程；模拟调制；模拟/数字转换；基带数字传输；带限信道的数字传输；载波调制的数字传输；信道容量和编码；扩频通信系统。 (This book Brooks/Cole Publishing (Thomson Learning Publishing Group, a subsidiary) in 2000 launched BookWare Series (BookWare Companion SeriseTM) of a kind. The book provides the advantage of the popularity-based student version of MATLAB on the computer to solve the " modern communications systems," This course covered almost all aspects of the analysis of ideas, methods, MATLAB script files and processing the results of examples, as well as independent study for students seminar to answer. The book consists of nine chapters, namely: Signal and Linear System stochastic process analog modulation analog/digital conversion base-band digital transmission band-limited channel digital transmission carrier modulation digital transmission channel capacity and coding spread-spectrum communication systems.)

简易的matlab程序,还请大家多多指教，另求有限元计算光纤模场的matlab程序，请大家指点(some easy programs of matlab)

函数的近似式，构造函数的逼近方法，从而得到比较准确的函数图象(Is often necessary to obtain the function approximation constructor approximation method)

基于MATLAB的FFT谐波频谱分析，利用FFT变换算法进行谐波的频率和幅值的变化分析，利用图形分析结果。(MATLAB-based FFT harmonic spectrum analysis using FFT transform algorithm changes the frequency and amplitude of the harmonic analysis, the use of graphical analysis results.)

强力推荐ISAR转台成像程序，发送线性调频波。ISAR成像在进行了平动补偿之后，模型等效为转台模型(The ISAR turntable imaging program is strongly recommended, and the LFM wave is transmitted. After the ISAR imaging is compensated for translation, the model is equivalent to a turntable model)

说明：  This provides good overview for post-processing by Matlab
