    • A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters is disclosed. Embodiments of the novel system and method enable a wireless communication system to determine if signals being received by system receivers arrive directly from a target mobile appliance or if the signals are passing through or via a repeater. In an embodiment, the system's repeaters use a co-channel AM Golay Hadamard sequence multiplied by an uplink signal to watermark the repeated signal. The system uses the known AM Golay Hadamard sequences of the repeaters and the waveform of the received uplink signal to detect whether a repeater has operated on the signal and which repeater operated on the uplink signal. Embodiments of the novel system and method provide system management data and can be used to provide more accurate geolocation of mobiles served by repeater stations.
    • 公开了一种在具有中继器的主机无线通信系统中操作的网络覆盖地理位置系统的新型系统和方法。 新颖的系统和方法的实施例使得无线通信系统能够确定系统接收器正在接收的信号是否直接从目标移动设备到达,或者信号是否经过中继器。 在一个实施例中,系统的中继器使用与上行链路信号相乘的同频道AM Golay Hadamard序列来水印重复的信号。 该系统使用中继器的已知AM Golay Hadamard序列和接收的上行链路信号的波形来检测中继器是否对信号进行操作,哪个中继器在上行链路信号上操作。 新颖的系统和方法的实施例提供系统管理数据,并且可以用于提供由中继站服务的移动台的更准确的地理位置。

    • A method for use in a wireless communication system with a network overlay geolocation system having a sparse deployment network in which base stations of the wireless communication system may or may not have a co-located wireless location sensors (WLS). The method enables detection and measurement of a target mobile's signal independently from a primary WLS located at the base station serving the target mobile, which enable location estimated in previous “no location” areas. The method selects based on predetermined criteria from one or more of several techniques that aid in the detection and determining a location for the target mobile. The method selects from timing advance, power levels, pattern matching, EOTD, speed, and pseudo range measurements to estimate the location of the mobile. The method also uses ambiguity function processing to detect the signal and measure an attribute of the signal.
    • 一种用于具有网络覆盖地理位置系统的无线通信系统的方法,所述网络覆盖地理位置系统具有稀疏部署网络,其中所述无线通信系统的基站可以具有或可以不具有同位置的无线位置传感器(WLS)。 该方法能够独立于位于服务于目标移动站的基站的主WLS来检测和测量目标移动台的信号,这使得能够在先前的“无位置”区域中估计的位置。 该方法基于有助于检测和确定目标移动站的位置的若干技术中的一种或多种的预定标准来选择。 该方法从定时提前,功率电平,模式匹配,EOTD,速度和伪距测量中选择,以估计移动台的位置。 该方法还使用模糊函数处理来检测信号并测量信号的属性。

    • A system and method is disclosed for determining the location of a mobile appliance using the reverse pilot channel provided in CDMA 2000 communication systems to determine an attribute (e.g., time of arrival, angle of arrival, time difference of arrival, received power level) of a reverse pilot signal at one or more wireless location sensors. A network overlay of wireless location sensors monitors the reverse pilot channel for a target mobile's reverse pilot signal. The monitored signal may be compared to a reference signal to determine a correlation and thereby determine an attribute of the target mobile's reverse pilot signal. The method may be performed independently from the communication system and without requiring retrieval of information bits from the mobile appliance. The reference signal may be generated from the unique long spreading code mask of the target mobile appliance which is typically a function of the ESN of the target mobile appliance.
