maple 它的图形功能非常强大, 足以提供更多的关于函数的信息. 当然, 如果需要, 它的图形作适当改进即可满足出版要求. (maple graphics functions are very strong, and to provide more information about the function, of course. If necessary, it can improve the graphics for proper publication meet)

fundamental principles of space-time coding for wireless communications

实现OPNET与MATLAB的联合编程功能。在OPNET建模过程中，添加本文件中的代码，即可在仿真运行过程中打开MATLAB引擎，实现OPNET与MATLAB的联合编程(OPNET and MATLAB realization of joint programming. In the OPNET modeling process, adding the code in the file, you can open the MATLAB engine during a simulation run, the realization of joint programming OPNET and MATLAB)

用的db2小波对图像进行分解重构，小波函数可以换(wavelet analysis of figure by db2 )

this code realize the two dimention esprit algorithm

本程序主要描述的是二维DOA的MUSIC算法，有对应的图(a algorithm about MUSIC 2D direction of arrival. It is a very good and it will give some help to you.)

设计了一种具有异周期毗邻结构的新型循环前缀,提出了相应的OFDM 频偏估计算法。该异周期毗邻结 构循环前缀由CP1 和CP2 两部分构成,使OFDM 符号具有双周期特征。通过引入较短的CP1 ,牺牲极少的资源, 可以有效克服现有频偏估计方法中的固定频偏估计范围的缺陷,同时具有频偏估计范围大,精度高的特点。(This paper proposes a heter2cycle abutted CP st ructure and a two2step OFDM carrier f requency calibration algorithm. The cyclic prefix of the new cyclic prefix is made up of CP1 and CP2 , which provide the character of double2cycle for OFDM symbol. By int roducing a short CP1 , the proposed algorithm can overcome the defect of fixed f requency off set estimation range in current f requency estimation method , and achieves larger f requency esti2 mation range while obtaining fine f requency calibration.)
