回声信道模型,双通道,无法正确识别的情况.(Echo channel model, dual-channel, can not correctly identify the situation.)

说明：  这是一个matlab程序用于构建人工神经网络模型，可以随意设置层数和单元个数！(This is a matlab program for building artificial neural network model can arbitrarily set the number of layers and units!)

communication system is expected to increase the service, the quality improvement and also the capacity, using spread spectrum communication system is one of the method to fulfill that demand. This quality and capacity factor will depend on the number of user. In order to see the performance of the Wiener Filter on the MC-CDMA system, simulation method is used by increasing the Direct Sequence Spread Spectrum CDMA signal, with digital modulation QPSK

说明：  实现4psk调制的源程序，以及对应的在白噪声信道下的系统性能(achieve 4psk modulation source, as well as corresponding white noise in the channel system performance)

有限元的程序，好用的，做毕业设计可以做参考(Finite element program, easy to use, do graduate design reference can be done)

说明：  假设微电网中有风、光、微型燃气轮机、蓄电池，且已知各时段负荷需求；微电网可并网运行，当微网内部发电量较大时，可向电网卖电，而当内部发电不足时，可从大电网购电，价格参考实时电价。考虑各机组运行成本、燃料成本、污染物处理成本、以及买卖电支出或收益。该程序可解决在并网运行模式下，各机组出力如何分配才能达到经济最优的问题。(Suppose there are wind, light, micro gas turbines and batteries in the microgrid, and the load demand is known at each time period; the microgrid can be connected to the grid for operation; when the microgrid has a large amount of internal power generation, it can sell electricity to the grid, and when the internal power generation is insufficient At that time, electricity can be purchased from the big grid, and the price can be referenced to real-time electricity prices. Consider each unit's operating costs, fuel costs, pollutant disposal costs, and trading power expenses or benefits. This procedure can solve the problem of how each unit's output can be distributed to achieve economical optimization in the grid-connected operation mode.)

很经典的空时编码书籍，英文版。 "Space-Time Coding Theory and Practice" writen by Hamid Jafarkhani Cambridge Pre(Is a classic space-time coding books, the English version. Space-Time Coding Theory and Practice writen by Hamid JafarkhaniCambridge Pre)

说明：  基于SVPWM技术的永磁同步电机仿真模型(SVPWM technique based on simulation model of permanent magnet synchronous motor)

Classify using the maximum-likelyhood algorithm(classifies using the maximum- likelihood al gorithm)

这里有几篇有关doppler frequency offset估计问题的相关文献，主要采用的是信道响应法，自相关法，循环前缀法来估计多普勒频移的。( Here are a few questions about the doppler frequency offset estimate of the relevant literature, is mainly used in the channel response, self-correlation method, cyclic prefix to estimate the Doppler frequency shift.)
