发明名称 Internal calibration method for receiver system of a wireless location system
摘要 An internal calibration method, used to calibrate a receiver system used in a wireless location system, comprises injecting a signal into the receiver system and utilizing the signal to obtain an estimate of the manner in which the transfer function of the receiver system varies across the bandwidth of the receiver system. This estimate is used to mitigate the effects of the variation of the transfer function on time measurements made by the receiver system. Such time measurements are used to locate mobile transmitters.
