说明：  Cognitive Radio systems with liscense and Rental Users in addtion to adding noise and attenuation.(Beautiful)

说明：  可进行位置识别,通过声源的波束形成,可知道其相关信息.再加上(can identify the location, source, a beam forming, know relevant information. Plus )

MATLAB教程 很详细 好好学啊 里面有源代码 值得一看(MATLAB tutorial is very detailed good school inside the active code worth a visit)

IE3D软件的很多教程，很好很强大！很珍贵的啊(IE3D software, many of tutorials, very good very strong! Ah very valuable)

可自行设置参数产生SCM信道，支持MIMO等功能(can set your own parameter to create SCM channel,support MIMO an other function.)

simulink 机理模型证明了道路的角度以及调整道路矩的影响，希望大家分享(The package contains a simulink model of a mechanism which verify the angle of the road and adjust the torques by giving a angle to a plate located under the load session.this model is not a very complicated one and would be useful to whom want to: 1.get familiar with control designs specially PID controllers 2.get familiar with linerizing nonlinear models )
