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.

应用背景 这是一套本人亲自开发的结合UML面向对象分析设计教程：“UML实战精要教程”的教学案例的实例程序。 演示如何利用UML分析设计方法从项目需求到最终编程实现一个应用软件实例。 而应用软件的实例取自做培训本身的一个需求：调查学员的培训需求。 实现的功能是： 多个学员可登录上线，提出培训要点，并围绕所有的培训的要点发表自己的意见。 教师登录上线，可查看全部学员提出的培训要点需求，并统计培训需求最高的培训要点，以做下一次的培训内容的准备。 培训要点按树形结构展示。 整个程序实际上实现的是一个多人同时在线编辑一个树形结构的树形编辑器。 关键技术 通过服务器接受登录在线的记录，并转发客户端请求到其他在线的客户端，其他客户端收到请求，同步修改各自本地的树形模型，实现分布式的模型同步构建。 服务器功能及其简单，只接受用户上线连接并透明转发（广播或定点转发）客户端请求。 学生客户端和教师客户端功能有所不同，可围绕同一个树形模型进行不同的操作。 提供了分布式模型构建的经典案例。 本案例只提供架构演变过程的最后版本。实际教学案例有演示架构演变过程的5个版本。 实战精要教程的教案将另行分享。

好东西cl_bobcycle "1" // fps_max 设定游戏的最高FPS数值，一般来说，应该与你显示器的刷新频率相 同.如果你的机器非常强劲，你可以把这个值设到100，否则，75就足够了. fps_max "75" // fps_moden 设定在网络联机时的最高FPS数值。如果设成0，那么这个参数会使 用fps_max的数值. -good things cl_bobcycle "1"// fps_max game set the maximum FPS values, in general, and you should display the same high frequency. If your machine is very strong, you can use the value set to 100, and 75 would be sufficient. Fps activated "75"// fps_moden set in on-line network at the highest numerical FPS. If set to 0, then this parameter will be used fps_max values.
