| 摘 要： | 介绍了一种适用于时分双工蜂窝移动系统，基于非线性判决反馈均衡器和递归最小平方算法的环形自适应阵列天线，研究了阵列波束对期望信号的增强和对干扰信号的抵消的形成过程，并分析了方向增益的收敛属性与训练序列的关系，计算机仿真结果表明了波束形成与接收信号到达角度之间的联系，发现了波束收敛所需训练序列的最佳长度。

| Abstract: | A kind of 8 element circular adaptive array antenna is proposed to time division duplex cellular mobile system, based on non linear decision feedback equalizer and recursive least square algorithm. The beam forming about steering to the desired signal and suppressing to the interference signal is studied, and the relationship between the convergence property for beam pattern and the training sequence is analyzed. Computer simulation results show the relationship between the beam pattern and the direction of arrivals, and the optimal length of training sequence required by the pattern convergence is discovered. |
