this is a whole OFDM project for Matlab

说明：  这是一个基本的CDMA系统的调制与解调系统。包括随机信号的产生，调制还有相应的解调。(This is a basic CDMA coding and decoding system, it includes random signal generator and coding and decoding modules )

用于绘制双曲地震同相轴，以便后续的处理工作，非常有用(draw hyperbolic events)

说明：  采用平面波展开法计算2维光子晶体的能带图(The plane wave expansion method two-dimensional photonic crystals with map)

说明：  基于agent图的脆性仿真程序，研究对象是船舶电力系统(Agent-based simulation program brittle graphs, study the ship power system)

计算面积，使用方便！是个测试Matlab的实例！(Calculate the area, easy to use! Test Matlab instance!)

Resource allocation in LTE matlab code

利用matlab进行QAM的误码率仿真。利用ofdm技术。(Using matlab QAM BER simulation. Use ofdm technology.)

实现带有再采样步骤的rjmcmc算法，并用算例证明其性能。(To achieve with the re-sampling step rjmcmc algorithm, and use examples to prove its performance.)

是数学竞赛的往年考题！！希望对大家有用！！(Mathematics exam in previous years the competition! ! Hope it useful! !)
