  • A modulation identification algorithm based on blind channel identification and equalization is proposed for MPSK and MQAM signals in multi-path environments. The channel order is estimated accurately first. Then, the eigenvalue perturbation analysis is done on the basis of matrix outer-product decomposition to get the more stable performance of channel blind identification and equalization. Finally, the multistage blind subtractive clustering method is used for the equalized constellation to determine the modulation type. Compared with the existing methods, it is a simple solution with smaller number of symbols for more modulation types and is more suitable for the practical application. Simulation results prove the effectiveness of the algorithm.
