bw_fragile_robust_cross
matlab编写的对二值图像的数字水印添加与提取程序。压缩包中有示例图片。可以添加水印,结果肉眼不易分辨出变化,不影响使用。可加入信息长度达100个字节。提取时可验证是否被修改过,如未修改,可提取隐藏信息。当有修改发生时,可以定位修改的位置,并在图上标出。标识面积占修改面积的75%,一般修改都能标出(matlab prepared binary image of the digital watermark added and extraction procedures. Compression package has sample images. Can add watermarks, the results of the changes are not easily distinguishable from the naked eye, does not affect use. Can be added to the information length of 100 bytes. Verifiable extraction has been modified, if modified, can extract hidden information. When a modification occurs, you can modify the location of positioning and marked maps. Logo area accounted for 75 to amend the area generally can be identified modifications)

BPSKQPSK_matlat
Consider a BPSK and a QPSK system for the following two cases: 1) The probability that the symbol 1 is sent and the probability that the symbol 0 is sent are all the same. 2) The probability that the symbol 1 is sent is two times than the probability that the symbol 0 is sent. Assume that the noise is Gaussian distributed with mean=0 and 2 = 1.
