在qpsk调制下实现ofdm的仿真 信道是高斯信道(qpsk ofdm awgn)

一本介绍matlab学习的书籍，清华出版 高清，非常有用(An introduction to the MATLAB learning books, Tsinghua publishing HD, very useful )

本文算法是将24 位真彩图的亮度分量分块 DCT ,然后利用DCT 量化系数的奇偶特性嵌入8 位灰度水印图,并通过PN 序列加密来保证水印的 安全性。算法中,将灰度图像转换为二进制数据 流,置乱后扩频调制,隐藏在宿主DCT 系数量化值 中,提取时不需要宿主信号,实现水印信号的盲提 取。(This algorithm is 24-bit true color pictures of the luminance component of block DCT, quantization DCT coefficients and then use the parity properties of 8-bit grayscale watermark embedding map, and through the PN sequence of encryption to ensure the security of the watermark. Algorithm, the gray image into binary data stream, scrambling after the spread spectrum modulation, hidden in the host DCT coefficient quantization values, the extraction does not require the host signal, the blind watermark extraction.)

该算法为fastica的c＋＋版版本，有很好的分离效果。 (The algorithm for the fastica the c++ Version, good separation.)

MATLAB程序开发经典英文教程，帮助开发人员更好的利用MATLAB开发。(MATLAB Programming classic English tutorial to help developers better use MATLAB development.)

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.)

本文介绍kalman滤波的基本原理及发展现状，主要从模型的建立和非线性模型的线性化两方面进行介绍(In this paper, the basic principle of kalman filter and the development present situation, mainly from the establishment of model and the linearization of the nonlinear model is presented in two aspects)
