关于分数频率复用(FFR)系统的C++程序仿真。分数频率复用技术是LTE系统中十分重要的分支。-This is code is the basic introduction of Fractional Frequence Reuse technique,which is a quite important branch of LTE communication system.

给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。-The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication

CDMA and OFDMA are the multiple access techniques for the next generation wireless communication systems. In 3G systems CDMA is used and in 4G OFDMA technique is used. Recently in 3G systems Wideband Code Division Multiple Access (WCDMA) is used beca
