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.)

Multiple input multiple output techniques combined
with orthogonal frequency division multiplexing (MIMO-OFDM)
provide a promising approach for wireless systems. However, a
serious drawback of the OFDM system is the high peak-toaverage
power ratio (PAPR), which may severely affect the
power efficiency of RF power amplifiers. In this paper, we
propose a simple method to reduce the PAPR of MIMO-OFDM
signals based on the use of unused subcarriers. Instead of
processing the signals at each transmitter separately, a peak
cancelling signal is generated at one antenna and is then applied
to all the others with only simple modifications. Simulation has
shown that a minimum 2 dB reduction in PAPR can be achieved
for all transmit signals using this approach. As the signal
processing is nearly all done at a single transmitter, repetition of
the operations at each transmitter is avoided, and therefore the
overall cost of the system can be significantly reduced.
