Modulation identification for MIMO-OFDM signals

Based on the higher order cumulates, OFDM signals are discriminated from single-carrier signals by the proposing feature. Determination of the modulation type for sub carriers of an OFDM signal is carried out in the paper by combined features. The performances of proposed algorithm are tested using Monte-Carlo simulations. It is shown by the results that the algorithm is stable with a low complexity and high percentage correct identification for the modulation identification of OFDM signals.
