摘要
随着CDMA蜂窝通信的推广应用和用户定位需求的日益增长,发展CDMA系统中的无线电定位技术已引起广泛关注,在国外已取得了一定的进展。文中结合国内外最近几年的发展情况,讨论了无线电定位技术的应用方向、在CDMA系统中定位的方法及算法、影响定位精度的因素及克服方法。
With code - division - multiple - access being deployed by more and more cellular or personal communications services providers, developing the wireless location technology in CDMA networks is imperative and there have been some progress made abroad. This article discusses the applications of location technology, the methods and algorithms for their implementation in CDMA networks and the error sources in wireless location and the methods to improve the location accuracy.
