Research on a modulation recognition method for the FBMC-OQAM signals in 5G mobile communication system
To solve the problem that the modulation mode of filter bank-based multicarrier (FBMC) with offset quadrature amplitude modulation (OQAM) signal in 5G mobile communication system cannot be identified by traditional methods, a novel modulation recognition method for FBMC-OQAM signal is proposed. This method combines the conventional logarithmic likelihood ratio decision with the feature of power spectrum sidelobe attenuation to distinguish the FBMC-OQAM signals from other multicarrier modulated signals. Simulation results demonstrate that the method can identify FBMC-OQAM signal when SNR is low.
