摘　　要：通过限制估计的方向向量与真实的方向向量之间的误差范数的边界,提出了一种基于二阶锥(Second Order Cone,SOC)规划的稳健四阶累积量盲自适应波束形成算法。该算法相较于采用传统对角加载技术的高阶累积量盲波束形成算法和WCPO-RCUM算法而言,进一步提高了稳健性和输出信干噪比。计算机仿真实验表明,该算法具有很好的稳健性。By imposing a bound on the error between the estimated signal steering vector and the actual signal steering vector, a new robust 4^th order adaptive cumulant beamformer is presented. The second order cone program is used to get the weight vector. The proposed algorithm achieves better robustness and higher output SINR than the previous one using conventional diagonal loading method and WCPO-RCUM. Excellent performance is demonstrated via simulations.
