An Improved Constant Modulus Beam-forming Algorithm
Hongliang Fu · Communications technology · 2009
The good convergence stability of the steepest decline CMA(SDCMA) and faster convergence of the least-squares CMA(LSCMA) in beam-forming applications is analyzed in this paper, to absorb the advantages of the both algorithms, a new combined blind beam-forming algorithm based on the pre-despread decision feedback(SD-LSCMA) is proposed.The proposed algorithm is simulated and compared with the traditional methods in the same environment, and the simulation results show that the proposed algorithm has a better anti-MAI performance.
