Embodiment Construction
[0085] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0086] In order to further improve the problems of slow convergence speed, large steady-state error, and high computational complexity of the blind equalization algorithm, the present invention proposes a dual-mode blind equalization method combining switching mode and weighting mode with CMA+DDLMS. Firstly, the performance simulation of three blind equalization algorithms, CMA, MCMA, and DDLMS, is carried out, and the advantages and disadvantages of the three blind equalization algorithms are analyzed, and two blind equalization algorithms, CMA and DDLMS, are selected. Then, combining the advantages and disadvantages of the switching dual-mode blind equalization algorithm and the weighted dual-mode blind equalization algorithm, the CMA+DDLMS dual-mode blind equalization algorithm combined with switching and weighting modes is simulated.
