多波束形成的代码，其中也有一些自适应的波束形成代码(beam forming)

本课件按逻辑编排，自始至终用实例描述；内容完整且每章相对独立；既适用于初学者，也适用于高级MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是一大特色。 本课件适合作为理工科高等院校研究生、本科生教学用，也可作为广大科研工程技术人员的自学。(The courseware is organized in a logical, throughout examples described complete and relatively independent of each chapter suitable for both beginners and for advanced MATLAB users. Combined with the description of MATLAB and FORTRAN, C, and other languages ​ ​ is a major feature. The courseware for science and engineering universities graduate, undergraduate teaching, can also be used as a self-study of the majority of scientific engineering and technical personnel.)

Sparse Signal Representation using Overlapping Frames (matlab toolbox)(Sparse Signal Representation using Overl apping Frames (Matlab toolbox))

a self- embedding block wise fragile watermarking scheme with tamper detection and content recovery capability. The proposed scheme embeds the shuffled extensive ten bit Recovery data and two bit Authentication data of the image block into the least significant bits (LSB) of its corresponding mapping block.The integrity of a test block is decided by comparing 2×2 non overlapping block of the test block with its corresponding mapping block. Experimental results show that the suggested scheme outperforms conventional self recovery fragile watermarking algorithms in alteration detection as well as in tamper recovery of the image.

least significant bit insertion is done using matlab..data is hidden in the least significant bit of carrier file.
