OFDM系统中提出一种改进方法对频偏的捕获, 在联合使用9个短前导序列和长前导序列估计算法的基础上,采用鉴频环路的方法来消除算法中的除法和取模运算 (OFDM system in an improved way of deviation of the capture, in the joint use of nine short leader sequence and the long preamble sequence estimation algorithm, based on the frequency discriminator method to eliminate the loop algorithm in the division and modulo operation)

选择两张图片，一张水印图，一张嵌入图，将水印图进行Arnold置乱算法将其置乱，嵌入到嵌入图中，形成数字零水印，选用白噪声、高斯低通滤波、压缩、剪切、旋转攻击测试。以此观察图像鲁棒性(Select two pictures, a watermark and an embedded graph. We will scramble the watermark image with Arnold scrambling algorithm and embed it into the embedded map to form digital zero watermark. We choose white noise, Gauss low pass filtering, compression, shearing and rotation attack test. To observe the robustness of the image)
