稀疏化的U-TDOA无线定位网络
摘要：
在叠加的基于U-TDOA的无线定位系统中，通常被与BTS定位在相同地点的LMU用于采集前向信道和反向信道中的无线电信令。采用技术来补偿稀疏LMU部署，在稀疏LMU部署中，U-TDOA服务区的扇区受到上行链路解调限制或下行链路信标发现限制。
摘要（英）：

In an overlay, U-TDOA-based, Wireless Location System, LMUs typically co-located with BTSs, are used to collect radio signaling both in the forward and reverse channels. Techniques are used to compensate for sparse LMU deployments where sections of the U-TDOA service area are uplink demodulation or downlink beacon discovery limited.
