A spectrum sharing method based on ATM
In recent years, the number of portable mobile terminal users is increasing with improvement of the wireless communication environment. In addition, mobile multimedia services also bring the increase of wireless traffic and lack of
spectrum resources. As a technique for efficient spectrum use, spectrum sharing receives much attention. It dynamically assigns a spectrum channel from a larger area network such as WiMAX to smaller area networks such as WiFi-based wireless LANs and achieves to increase the total wireless communication capacity of this area. In a case where all providers are cooperative, the spectrum sharing can be realized easily and improve user throughput in average. In another case where providers are not
cooperative, some spectrum trading methods based on auction theory had been proposed.

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.)

Abstract—In this paper, we study the joint estimation of inphase
and quadrature-phase (I/Q) imbalance, carrier frequency
offset (CFO), and channel response for multiple-input multipleoutput
(MIMO) orthogonal frequency division multiplexing
(OFDM) systems using training sequences. A new concept called
channel residual energy (CRE) is introduced. We show that by
minimizing the CRE, we can jointly estimate the I/Q imbalance
and CFO without knowing the channel response. The proposed
method needs only one OFDM block for training and the training
symbols can be arbitrary. Moreover when the training block
consists of two repeated sequences, a low complexity two-step
approach is proposed to solve the joint estimation problem.
Simulation results show that the mean-squared error (MSE) of
the proposed method is close to the Cramer-Rao bound (CRB).
Index Terms—MIMO OFDM, CFO, I/Q imbalance, channel
estimation.
