ESPRIT_DOA
说明: ESPRIT方法进行DOA估计,各种参数见程序内部的参数设置,只是简单的ESPRIT程序,而非修正的ESPRIT方法(ESPRIT DOA estimation methods, see the program within the parameters set of parameters, but simply the ESPRIT program, rather than the ESPRIT method of correction)

提出了一种可抗
几何攻击的二值文本图像水印算法. 该算法基于DCT,它将二值图像的DCT、图像的视觉特征向
量和加密技术有机结合起来,在提取水印时不需要原始图像,是一种实用的盲水印算法(We propose a geometric attacks against Binary Text Watermarking Algorithm. The algorithm is based on DCT, it binary image DCT, the image of the visual feature vector and encryption technology combine in the watermark without the original image is a practical blind watermarking algorithm)

A_Software_Defined_GPS_and_Galileo_Receiver
Software-defined radios (SDRs) have been around for more than a decade. The
first complete Global Positioning System (GPS) implementation was described
by Dennis Akos in 1997. Since then several research groups have presented their
contributions.We therefore find it timely to publish an up-to-date text on the subject
and at the same time include Galileo, the forthcoming European satellitebased
navigation system. Both GPS and Galileo belong to the category of Global
Navigation Satellite Systems (GNSS).
