了低信噪比﹑多径瑞利衰落信道条件下，基于高阶累积量的OFDM信号盲识别技

术。提出了利用奇数阶累积量区分OFDM信号与单载波信号的方法，并对基于三

阶和五阶累积量的算法进行了仿真分析。

-﹑ Focus on the low SNR multipath Rayleigh fading channel conditions, based on cumulant OFDM signal blind identification technology. Made a distinction between the use of odd-order cumulants single-carrier OFDM signal with the signal approach, and based on the cumulative amount of third-order and fifth-order algorithm for the simulation.
