摘要
论文分析研究了最陡下降恒模算法(SDCMA)在波束形成应用中收敛稳定性好和最小二乘恒模算法(LSCMA)收敛速度快的特点,将两种算法以新的方式相结合,吸收二者的优点,提出了一种基于预解扩判决反馈盲波束形成组合算法(SD-LSCMA)。通过和传统算法在相同环境下进行MATLAB仿真比较,结果表明,文中提出的算法具有更好的抗强多址干扰性能。
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.
