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.

软电话 从功能分为：服务器端和客户端 服务器：记录所有客户的信息，对客户的登陆、注销等请求进行响应 客户端：利用UDP协议与服务器和被叫或主叫客户端进行通讯 点对点通讯中的请求和响应消息是通过SIP协议来完成传输的，音频信息（压缩后）是同构RTP协议来完成传输的-Soft phone functionality is divided into: server-side and client-server: a record of all customer information, customer landing, write-offs, such as in response to client requests: the use of UDP protocol with the server and the called or caller client communication point of point communication in the request and response messages through the SIP protocol to complete the transmission, audio information (compressed) is isomorphic RTP protocol to complete the transmission

应用背景以太网交换机所使用的以太网控制专用芯片多具有SMI接口,以实现对芯片的控制。考虑到以太网交换机的节能趋势,使用ARM芯片s3c2440作为以太网专用芯片的主控器件,使用软硬结合的方法,设计并实现了单片机系统与SMI接口的通信,介绍了SMI接口的特征和时序,并以以太网控制芯片88E6097为例,给出了在ARM芯片s3c2440上用I/O实现SMI接口的硬件电路和相关程序。关键技术基于c语言的SMI接口模拟，88E6097交换芯片的寄存器读写访问，88E6097芯片VLAN技术。采用ARM芯片s3c2440基于Linux的操作系统，通过c语言编程模拟SMI接口，对88E6097交换芯片的寄存器进行读取、写等操作，以达到对88E6097交换芯片基于802.1Q的VLAN配置。

贝叶斯滤波如卡尔曼滤波，粒子滤波等，给定一线性或非线性动态系统，用已知的观测数据和动态向量求后验概率。该资源是贝叶斯滤波器的C++类库，里面包括卡尔曼滤波（kalman filter）、粒子滤波（particlefilter）等。希望对想用C++实现滤波算法的同学有所帮助！
