The unlicensed 60 GHz industrial, scientific and medical (ISM) radio band provides a wide bandwidth for wireless high data rate communication systems. To optimally utilize these millimeter wave data transmission channels, exploiting orthogonal polarizations is a crucial enhancement. Along with the increase in data rate, improvements of the robustness of communication links in wireless local/personal...
Types and characteristics of information on examination certificates are analyzed in this paper and then the two-dimensional bar code encoding method based on GB18030 character set of information in text kind, and the method for image kind on the basis of compression using zerotree of wavelet transformation is put forward. A flowgraph for the whole procedure is given and an example of examination...
