摘要： One illustrative embodiment takes the form of a system for locating wireless transmitters employing an Orthogonal Frequency Division Multiplexing (OFDM) digital modulation scheme. The OFDM scheme comprises transmitting signal components over narrowband frequency channels spanning a wideband channel. The system includes a first receiving system configured to receive a fraction of the signal components transmitted by a first wireless transmitter to be located in a fraction of the narrowband frequency channels, and to process the fraction of the signal components to derive location related measurements. The system further includes at least a second receiving system configured to receive the fraction of the signal components transmitted by the first wireless transmitter, and to process this fraction of the signal components to derive location related measurements. The system also includes a processing system configured to use location related measurements from the first and second receiving systems to compute the location of the wireless transmitter.

摘要： Various aspects are disclosed herein for determining a location estimate for multi-mode mobile devices using measurements from one or more radio access technologies and providing a combined location solution. Using the multiple radio access technology capability of the wireless communications system, a mobile communications device may be located on a first radio network characterized by a first radio modulation technique, radio network topology, and channel bandwidth. The mobile communications device may then be handed off to a second radio network and located using a second radio network characterized by a second radio modulation technique, radio network topology, and channel bandwidth. The two location estimates may then be used to develop a combined location estimate.

摘要： A method and apparatus for position determination is provided using measurements from both Global Positioning System (GPS) receivers and terrestrial-based Uplink Time Difference of Arrival (UTDOA) receivers. The method involves the transformation of downlink satellite measurements into equivalent UTDOA measurements by computing comparable cross-correlation coefficients and time differences of arrival with respect to a UTDOA reference station. The method includes a weighting operation whereby the relative weights of the UTDOA measurements and the relative weights of the GPS measurements are adjusted based on a theoretical scaling followed by empirical adjustments. The method further involves the efficient computation and combining of metrics that are used to minimize the weighted error between candidate location solutions and the UTDOA and GPS measurements.
摘要翻译：使用来自全球定位系统（GPS）接收机和基于地面的上行链路到达时差（UTDOA）接收机的测量来提供用于位置确定的方法和装置。该方法涉及通过计算相对于UTDOA参考站的可比互相关系数和到达时间差来将下行链路卫星测量转换成等效的UTDOA测量。该方法包括一个加权操作，其中UTDOA测量的相对权重和GPS测量的相对权重基于经验调整后的理论缩放来调整。该方法还涉及用于最小化候选位置解决方案与UTDOA和GPS测量之间的加权误差的度量的有效计算和组合。

摘要： In a network-based Wireless Location System (WLS), geographically distributed Location Measurement Units (LMUs) must be able to detect and use reverse channel (mobile to network) signals across multiple BTS coverage areas. By using Matched Replica correlation processing with the local and reference signals subdivided into discrete segments prior to correlation, the effects of mobile clock drift and Doppler shifts can be mitigated allowing for increased processing gain.
