D2D发现信道matlab代码，包括资源池的确定，随机撒点确定用户，为用户分配数据流，资源分配过程，SINR计算(D2D discovery channel matlab code, including determining resource pool of randomly scattered points to determine the user, assign the user data stream, the resource allocation process, SINR calculation)

贝叶斯网络的matlab实现。可以创建贝叶斯网络、训练模型，以及实现统计推理。这里是最新的1.0.4版(Bayesian networks to achieve matlab. Bayesian networks can be created, the training model, and the achievement of statistical inference. Here is the latest version 1.0.4)

dijkstra算法的matlab程序，用于优化路径规划的初始路径，只能做出一个次优的结果，以后可以用很多优化算法来进一步优化(dijkstra the algorithm matlab procedure, uses in to optimize the way plan the initial way, only can make an order superior result, later will be allowed to use the very many optimized algorithm further to optimize )

本文对于非线性非高斯问题，提出了一种改进扩展卡尔曼滤波（NIEKF）新方法。该方法将迭代滤波理论引入到扩展卡尔曼滤波器方法中，有效地重复利用新的测量信息，还利用Levenberg-Marquardt 方法调整预测协方差阵以保证算法具有全局收敛性。实验结果表明，所提方法具有更高的估计精度，是一种效率较高、性能较好的跟踪方法。(This non-Gaussian for nonlinear problems, an improved extended Kalman filter (NIEKF) the new method. The method of iterative filtering theory is introduced to the extended Kalman filter method, the effective measurement of repeated use of the new information, also using Levenberg-Marquardt method to adjust the covariance matrix of prediction algorithm to ensure global convergence. Experimental results show that the proposed method has higher estimation accuracy, is a high efficiency, good performance tracking methods.)
