【摘要】 为了克服 NL OS信号对移动无线电定位的影响 ,对 TD- SCDMA系统中联合 DOA与 TOA实现移动终端定位的方案进行了研究。基于 NL OS信号识别的算法有效地解决了 NL OS信号对实施定位的影响 ,提出了一种对多基站时间加权定位算法。通过仿真实验证明了所采用算法的可行性 ,在 NL OS情况下也可满足 FCC对 E- 911业务的要求更多还原

【Abstract】 A way of joint TOA and DOA for wireless location applied in TD SCDMA is introduced, which resolves the NLOS problem based on NLOS signal detection algorithm. The simulation result shows that the location algorithm is feasible for TD SCDMA and it satisfies FCC’s demand about E 911 services even in NLOS environment.更多还原
