摘要：
The traditional methods of blind equalization for orthogonal frequency division multiplexing(OFDM) systems have the problems of slow convergence rate and short received data. A novel blind equalization method of OFDM systems based on the multi-modulus hybrid algorithm and variable step size iteration of inter symbol interference is proposed to solve this problem. Piecewise multiplexing of the received data is adopted in this method, and then the modified constant modulus algorithm and the decision directed algorithm are mixed into the multi-modulus hybrid algorithm. This equalization method is utilized by the variable step size iteration based on inter symbol interference. Simulation results show that the proposed method has not only more stable convergence performance but also faster convergence speed than the traditional equalization methods in non-cooperative communication. © 2016, The Editorial Board of Journal of Xidian University.
