摘要
本文提出了一种新的蜂窝网混合定位算法。该算法首先将服务基站智能天线阵列提供的信号路径损失差(SADOA)与到达角(AOA)信息相结合,然后通过WLS算法实现对移动台实际位置的估计。本算法结构简单,计算量较小且无需移动台与基站的时间同步。仿真结果表明,该算法能够有效减小阴影效应造成的估计误差,具有较高的定位精度。
A hybrid SADOA/AOA location method for wireless communication system is proposed in this paper. The signal attenuation difference of arrival and the angle of arrival derived from the smart antenna array of the service base station are combined first,and then the real position of the mobile station is estimated by using the WLS method. This algorithm is simple and can save the compu-tation cost,which does not need full network synchronization. Simulation shows that the proposed method has better accuracy and...
