qpsk通信系统的MonteCalo仿真程序，得到在Awgn信道条件下的误比特率曲线-MonteCalo communication system qpsk simulation program, the conditions at Awgn channel bit error rate under the curve

此程序完成MIMO各个自程序的功能，比如编码，信道仿真，信道估计，信噪比计算等，各子程序能够独立运行，具有很好的参考价值-This procedure since the completion of all procedures MIMO features, such as coding, channel simulation, channel estimation, signal to noise ratio calculation, the subroutine can be run independently, with a very good reference value

QR 二维码符号规格（不包括空白区）21×21 模块到177×177 模块（版本1到40，每版本符号每边增加4 个模块）。每个符号的数据字符数（最大规格的符号—版本40-L）数字数据为7089 个，字符字母数字数据为 4296 个字符，8 位字节数据为2953 个字符，日本汉字数据为1817 个字符，中国汉字数据为21008 个字符 。[21]Marks & Spencer 是第一家在英国包装市场上使用这种编码的公司。零售商介绍到在今年的早些时候，他们已经在所有果汁包装上使用这种编码上进行了8 周的试验。顾客能通过扫描解码得到每天提供的包括产品的趣闻，细节等信息。Marks& Spencer 高级包装技术师马克思高尔(Mark Caul)说:“QR 二维码是一个不靠增加包装尺寸或者标签空间而和顾客进行交流的梦幻机会。通过使用移动手机技术，能获得这种产品的原始故事或者在这款包装背后的故事，更有甚者，能获得使用须知的电影视频，这一切的一切都能在手机屏幕上剪裁播放。” Mar

USB_to_Serial vb与usb转串口的通讯-USB_to_Serialvb with usb to serial communication

This paper addresses the specific issues that a design team will have to consider in creating solutions for embedded devices. Starting with a generic architecture, issues regarding the creation of the hardware target and concomitant software are presented. Bluetooth system operation is then briefly discussed with the intention of taking into account the unique needs of a wireless connection in structuring the application software. Implementation issues are then discussed and closely followed up with development ideas that are designed to not only contain the project burn rate but also to get the product to market in as short a time as possible. - This paper addresses the specific issues that a design team will have to consider in creating solutions for embedded devices.
