摘要
文中通过对OFDM发射信号的分析,发现其与多径信号从形式上具有一定的可比性,进而通过仿真从统计意义上证明了OFDM发射信号同样具有分形特性,并利用分数布朗运动的特性对OFDM信号进行了重构,得到了较好的结果。为分形理论在OFDM系统中的应用奠定了一定的基础。
In this paper,compared with multipath signals,OFDM transmit is the same with them to some extent.Base on it.a lot of simulations have been done which proved OFDM transmit owns fractal characteristics too.Then the transmit is rebuilt on fractal theory,and the result is good enough.So the conclusions from this paper establsh a good foundation for the application of fractal theory in OFDM system.
