摘要
智能天线在第三代移动通信定位中的运用,使信号来波角的测量成为可能,提出在基于TDOA/AOA定位算法的基础上,引入松弛变量,采用反复叠代的方法,消除了大部分NLOS的影响,提高了定位精度.因此,这种方法适合于未来移动通信定位系统的应用.
With the use of smart antenna in the third generation of mobile communications location, it is possible to measure the angle of the arrival of signals. By introduction of loose variables in location parameters and using iterative calculation on the basis of TDOA/AOA location algorithm, most of the influence of NLOS propagation can be eliminated, and the location accuracy is increased. This method is good for the futural cellular network location.
