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.

应用背景这个程序将包括一个客户端和一个服务器。客户需要注册它本身服务器第一次使用简单的凭据（这些凭据的确切细节是留给你的决定）。这些凭据将被服务器用来验证客户的任何进一步会议。在客户端验证后，服务器将接受请求从客户端传送一个文件。如果请求的文件存在，那么它将被发送到客户。文件内容将被加密，使用一些简单的技术，如安全前提供的爪哇传播。如果被要求，文件不存在时，服务器将显示一个错误信息和关闭套接字连接。必须进行检查以确保文件传输成功完成（即，原文件及其副本在服务器上的内容相同）。如果转让不成功之后，任务就应该自动进行重试。一定的重试次数后（一个可以调整的参数），一个失败的消息应该是显示如果传输仍然不成功和套接字连接应该关闭。2）设计的服务器，它可以接受多个并发请求，使用爪哇的线程，然后你会得到一个额外的信用。你的程序应该处理适当的例外；关键技术FTP服务器的客户端加密 ；并发多线程
