说明：  数据通道剥离伪码后的载频估计,数据通道剥离伪码后的载波估计问题。对直接序列扩频系统的数据通道，假定接收设备已“完美”地锁定接收信号伪码，并实现了伪码剥离其中，信号幅度、电文、载波多普勒和载波相位均未知。电文的速率为10Hz。由于信源与接收端信号传输时延的不确定性，收到的信号电文是从某个未知时刻开始的。 利用数据文件 估计信号幅度、载波多普勒和载波相位(Data channel after stripping pseudo-code carrier frequency estimation)

认知无线电频谱检测中的能量检测模型的构建，以及产生不同信噪比的pf和pd的概率(Detection of Cognitive Radio Spectrum Detection Model for the energy and produce different signal to noise ratio of the probability pf and pd)

this paper examines the specific role played by a key component of OSNs: the extremely popular and widespread set of third-party applications on some of the most popular OSNs. With over 81,000 third-party applications on Facebook alone, their impact is hard to predict and even harder to study.

TSP问题的人工蚁群算法中，假设m只蚂蚁在图的相邻节点间移动，从而协作异步地得到问题的解。每只蚂蚁的一步转移概率由图中的每条边上的两类参数决定：1、信息素质，也称信息素痕迹。2、可见度，即先验值。(Artificial ant colony algorithm TSP problem, assume that m ants move between adjacent nodes in the graph, which asynchronously collaborate get problem solution. Each ant transition probability is determined by the figure of two kinds of parameters for each edge: 1, the quality of information, also called pheromone trails. 2, visibility, ie priors.)
