优化问题中，用八种不同的方法寻求问题的最优解。(Optimization problem, with eight different method of seeking the optimal solution of problem. )

PSO and OFDM power allocation system

应用MATLAB工具箱在VC++中实现神经网络的程序设计(MATLAB toolbox application in VC++ in the realization of neural network programming)

说明：  在VC++中调用Matlab引擎的两个例子(In VC++ calling Matlab engines in the two examples)

说明：  遗传算法解决TSP问题,地图为美国地图绘制边界.(Genetic algorithm to solve TSP, mapping the boundary map for the United States.)

由于实际信道中的多径和阴影效应，单个认知用户频谱感知的性能受到影响，因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制，即两用户进行协作频谱感知，提高主用户的检测率，减少检测时间，并且得到捷变增益。要求给出仿真结果。(As the actual channel of the multi-path and shadow effect, a single user of spectrum sensing of cognitive performance are affected, it needs to depend on collaboration between different users of spectrum sensing to combat multipath and shadow effects. The design requirements in the text using a cooperation mechanism, namely, two user collaborative spectrum sensing, to improve the detection rate of the primary users, reducing detection time, and get agility gain. Required to give simulation results.)
