In order to analyze the advantages and disadvantages of the algorithm, it is compared with the non-blind equalizer based on the LMS algorithm and the RLS algorithm, and the system bit error rate, constellation diagram and convergence curve of three different equalization algorithms are given. The simulation results show that the modeling method of the constant modulus blind equalization algorithm in this paper is correct, and it has good performance for time-varying channel equalization, and the system bit error performance is very good, and the algorithm does not require any prior knowledge of the input signal. At the same time, this paper also points out that the algorithm has the disadvantages of slow convergence and high system bit error rate.
