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.

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 Arπval (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 ofmetries that are used to minimize the weighted error between candidate location solutions and the UTDOA and GPS measurements This is done efficiently in two dimensions for UTDOA and in three dimensions for GPS measurements by increasing the complexity of searching operations as the optimal location solution is approached

摘要： In a Wireless Location System (WLS) deployed in connection with a CDMA-based wireless communications system, Location Measurement Units are used to collect multi-path corrupted radio signaling for use in time difference of arrival (TDOA) and hybrid positioning methods. Signal processing techniques are used to enhance the WLS's ability to determine the minimally time- delayed multi-path component and thus increase the accuracy of the TDOA location in CDMA-based wireless communications systems. The signal processing includes a filtering technique for reducing the leading sidelobes of the cross-correlation function as well as a leading edge discovery procedure.

摘要： 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： A large volume of high accuracy location data is determined in many commercial wireless networks from location based services (LBS) and, in the United States, for E911. Uplink-Time-Difference-of-Arrival (UTDOA) and Assisted GPS (AGPS) are the predominant geolocation technologies providing these high accuracy locations. In the US alone over 10 million wireless subscribers are located every month because they dial the national emergency number "911" on their mobile phones. This rich set of location data provides an a priori distribution of the location of subscribers in the wireless network. All digital wireless communications networks have a mechanism for the subscribers to time synchronize their handsets to the network. This mechanism provides a band of ranges from the serving cell site to the handset. An a posteriori location estimate can be determined very quickly by considering the a priori distribution of callers in the range band that the current subscriber is in.
摘要翻译：在许多商业无线网络中，从基于位置的服务（LBS）和在美国的E911确定了大量的高精度位置数据。上行 - 时差到达（UTDOA）和辅助GPS（AGPS）是提供这些高精度位置的主要地理位置技术。在美国，每个月都有超过1000万无线用户位于他们的手机上拨打国家紧急号码“911”。这种丰富的位置数据集提供了无线网络中用户位置的先验分布。所有数字无线通信网络具有用于用户将其手机时间同步到网络的机制。该机制提供从服务小区站点到手机的范围的频带。通过考虑当前用户所在的范围频段内的呼叫者的先验分布，可以非常快速地确定后验位置估计。
