摘 要: 基于频率不变思想,提出一种适用于宽带无线通信系统下的,新的宽带自适应天线阵列。能在信号频带范围内,保持天线阵列响应基本不变。同时通过窗函数来控制旁瓣的幅度。相对于传统的宽带自适应天线阵列,具有收敛速度快,复杂性低的特点。 Based on the idea of frequency invariant, a wideband adaptive antenna array is proposed for wideband wireless communication system. With the algorithm, the array beam pattern remains basically the same within a wide frequency range of interest. At the same time, the level of sidelobe can be controlled through windows function. In comparison to the conventional wideband adaptive antenna array, the new algorithm offers a faster convergence rate with a lower computational complexity.
