| 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,提出了一种新的稳健CAB（周期自适应波束形成）盲自适应波束形成算法。该算法克服了方向向量失配引起的自适应波束形成器的性能劣化问题。计算机仿真试验表明,较采用传统对角加载技术的R-CAB盲波束形成算法和WCPO-CAB算法而言,该算法进一步提高了稳健性和输出信干噪比。

| Abstract: | By imposing a bound of the error between the estimated signal steering vector and the actual signal steering vector,this paper present a new robust adaptive beamformer based on CAB algorithm using second-order cone program.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 which uses the conventional diagonal loading method and WCPO-CAB.Its excellent robust performance is demonstrated via two numerical examples. |
