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.)

Solving
说明： 求解双层规划问题常用的算法有极点算法、直接搜索法、下降法和非数值优化方法(如模拟退火算法、遗传算法等)，遗传算法的求解思路是：首先对上层的决策变量编码，代人下层规划模型，通过求解下层模型的决策变量值，代入上层模型计算适应度值，然后进行交叉、变异、选择操作，最后求出最优解。(Solving Bilevel Programming Problems with pole algorithm commonly used algorithms, direct search method, descent and non-numerical optimization methods (such as simulated annealing, genetic algorithms, etc.), genetic algorithm for solving approaches: the first on the top of the decision variable coding, on behalf of the were lower programming model, by solving the lower model of decision variables values into the upper model on behalf of the fitness value, and then crossover and mutation, select Options, and finally get the best solution.)

一种基于高阶累积量的数字调相信号识别方法
对当前通信信号中常用的数字调相信号BPSK、QPSK、1／4一QPSK、8PSK的调制识别问题，提出了一种基于信号差分高阶累积量的识剐算法。该算法分两个层次进行调制识别，首先利用信号的四阶累积量特征对BPSK、QPSK和{1／4一QPSK、8PSK}信号进行识别，然后再利用信号差分的四阶和八阶累积量特征对1/4-QPSK、8PSK信号进行识别。从理论上分析了的该算法的有效性，并通过计算机仿真验证了算法具有良好的性能。(A recognition algorithm based on differential high-order cumulant is proposed for the modulation recognition problems of BPSK, QPSK, 1/4-QPSK and 8PSK, which are commonly used in current communication signals. The algorithm is divided into two levels for modulation recognition. Firstly, BPSK, QPSK and {1/4-QPSK, 8PSK} signals are identified by using the fourth-order cumulant characteristics of signals, and then 1/4-QPSK and 8PSK signals are identified by using the fourth-order cumulant and eighth-order cumulant characteristics of signal difference. The validity of the algorithm is analyzed theoretically, and the good performance of the algorithm is verified by computer simulation.)
