产生随机数．产生的随机数服从（０，１）正态分布

已成功实现串口通讯测试，并可移植到其他的c#项目中去，该程序不是调用c sharp 控件实现的！是通过自建类文件实现的！移植起来也相当的方便，可根据自己需要增加16进制发送和接收，程序代码已注释，可根据情况修改和进行二次开发！

windows系统，qt creator2.4.1基于qt4.7.4（32bit），用多线程实现串口通信，编译成功，注意下载后，要选择你下载路径下的工程文件夹昨晚编译路径，不然无法修改调试。还有就是这个路径里不能有中文字符，不然无法编译成功。

中文RFC文件，无需翻译，对学习很有帮助！

因特殊的业务需要，某些电话交流需要在第三方的监视下进行，假定某电话交流由甲乙丙三方发起，丙为监听控制方，当甲开始说话时，丙可以不允许乙听，并且开始录音，当甲说完时，丙确定是否可以让乙听，如可以。给乙放录音，当乙说话时，重复以上操作。-because of special operational needs, some telephone exchanges in the surveillance of third parties under the assumption that a telephone exchange was launched by the tripartite B, and C to monitor the controlling party, began to speak when the A, B C can not listen, and began recording at the end when A and C to determine whether or not they can B listen, if we can. B recordings to release, when the B words, to repeat the operation.

WiMAX, or the IEEE 802.16 standard for broadband wireless access, is increasingly gaining in popularity as a technology with significant market potential. This paper first provides an overview of the existing and developing 802.16 standards and their key differences/applications. The PHY and MAC layers of a typical WiMAX base station are then described. The associated implementation challenges faced by WiMAX infrastructure developers, including performance/cost/flexibility trade-offs in the choice of silicon, are clearly outlined. The paper then describes how FPGA-based system implementation can address these challenges including the “accelerated time-to-market” requirement which is considered a key enabler for early success in this market. As an example design, the physical layer implementation of the 802.16d standard with Altera FPGAs and intellectual property (IP) is proposed.
