Abstract :
In this paper, a modified CMA-DDLMS equalization algorithm based on the automatic switch according to SNR is proposed. This modified algorithm overcome the shortcoming of large residual error and preserves the fast convergence performance. The simulation results confirm the effectiveness of the proposed algorithm on HF QAM signal The paper also gives the implementation procedure of the algorithm on TMS320C6711
