说明：  提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块，对每一块进行奇异值分解后，选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。(A new wavelet transform based on discrete (DWT) and Singular Value Decomposition (SVD) combination of digital image watermarking algorithm. The algorithm for wavelet decomposition of the original image and wavelet decomposition low-frequency sub-band are divided into blocks, each a singular value decomposition, the selection of each block by the largest singular value methods to quantify Arnold scrambled after embedding the watermark .)

这是一个OFDM基于WLAN系统的matlab仿真程序，源代码程序采用了导频符号辅助的OFDM调制机制，采用这种机制对系统误码率进行了仿真。(This is a matlab simulation cede of OFDM based WLAN system used in ETSI BRAN,IEEE 802.11 and ABIB MMAC projects. The program code adopted the pilot symbol-aided OFDM modulation scheme and evaluated the BER performance in the scheme. )
