随着网络带宽的越来越大以及嵌入式技术和嵌入式设备的日益发展成熟，过去的很
多设备如今变成了可管理的网络设备，它们不仅嵌入了操作系统和拥有自己的IP 地址，而
且还通过嵌入web 形式的网络代理端以方便用户的控制和管理。本文通过在arm920t 的开发
板上移植BOA（一个开源的web server），并嵌入到接入网络设备当中以实现对其进行web
化的控制和管理。(With increasing network bandwidth and embedded technology and the increasing development of sophisticated embedded devices, over the past many devices now become manageable network equipment, which not only embedded operating system and has its own IP address, and through web forms embedded in the network proxy client to facilitate the user' s control and management. In this paper, the development board in arm920t transplant BOA (an open source web server), and embedded in the access network equipment for them to achieve their web based control and management.)

针对MIMO-OFDM系统中期望最大化(EM)信道估计算法在高信噪比(SNR)下带来的误差地板(EF)现象,且OFDM符号的数据传输效率随发射天线数的增加而明显降低,提出一种改进的高效EM信道估计算法。该算法首先引入一种准确的等效信号模型并推导出一种修正的EM算法,改善了EM算法在高SNR下的性能 在多个OFDM间利用相位正交导频序列来提高数据传输效率,同时进行联合信道估计以提高估计性能。仿真实验验证了所提算法具有更高的信道估计性能和更高的数据传输效率。(For multiple-input multiple-output with orthogonal frequency division multiplexing(MIMO-OFDM) systems,the error floor(EF) phenomenon at high signal noise rate(SNR) was induced by the expectation maximum(EM) channel estimation algorithm.In addition,the data transmission efficiency was declined obviously with the increasing number of transmit antennas.According to these problems,an improved and efficient EM channel estimation algorithm was pro-posed.Firstly,an accurate and equivalent signal model was introduc...)
