很好 我采用得是串行方式对bp网络进行训练，为何训练时误差dsum约来越大？？望指教！(good, I have used in serial mode is the right bp network training, training errors are about to dsum greater? ? Look weekend!)

matlab教程，详细的介绍了matlab的使用方法，操作步骤基流程(matlab tutorial matlab detailed introduction to use, step-based process operations)

关于QPSK星座图的部分程序，本人搜索到的，感觉挺好的，大家可以看看，参考一下。(QPSK constellation diagram on the part of the process, I searched, feeling quite good, we can see that reference.)

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)

基础的PSO算法程序，可以方便的解决优化问题，也可以在此基础上方便的进行改进(Based on PSO algorithm program, you can easily solve the optimization problem, on this basis can also be easily be improved)

This paper presents a topology design scheme (HeteTopo) for QoS-based heterogeneity ssues in overlay multicast. The scheme aims at constructing a topology tree with differentiated QoS support for heterogeneous multicast service while optimizing the related tree cost metrics
