An algorithm for identifying multi-carrier modulated signals(OFDM) from single-carrier modulated signals(MPSK,MQAM and MFSK) in Rayleigh fading channels is presented.The algorithm directly processes bandpass signals without the prior information about the carrier frequency and the baud rate of received signals.The joint estimation of the signal to noise ratio(SNR) and the feature value based on higher order moments can realize the automatic recognition.Simulation results show that the classification rate reaches over 95% when SNR is above 0 dB.

提出一种R ay le igh衰落信道条件下的多载波调制盲识别算法,用以区分多载波调制信号(如OFDM)和数字单载波调制信号(如M PSK,M QAM,M FSK)。该算法不需要预先知道信号的载波频率和波特率,只需从中频信号直接进行识别处理。算法中利用信号的高阶统计量作为分类特征,采用信噪比(SNR)与特征参数联合估计的方法完成自动分类,仿真结果表明在SNR高于0 dB时识别率大于95%。

Gabor transformation is the improvement of FFT via short windows and it can better represent the instantaneity.Gabor transformation is introduced to solve the problem of identifying the modulation format of an incoming signal.By means of computer simulations and the theories analysis,the features of ASK,FSK and PSK are extracted.At the end,a modulation recognition algorithm and the results of computer simulations are given.

Gabor变换通过加窗函数的办法对Fourier变换加以改进,能较好地刻画信号中的瞬态结构。本文把Gabor变换引入到了数字通信信号调制盲识别领域,对ASK、FSK和PSK信号的Gabor变换域特征进行了理论分析和软件仿真,最后给出了识别算法和仿真结果。
