Abstract: A parameter estimator for estimating one or more parameter(s) from a signal is described. A correlation function is derived from the signal, and the correlation function analyzed to determine if one or more first peak(s) (312) are present, and, if so, distinguishable from the sidelobe(s) (318) of a second peak. If the one or more first peak(s) (312) are present and distinguishable from the sidelobe(s) (318) of the second peak, the one or more parameter(s) are estimated from the one or more first peak(s). If the one or more first peak(s) are not present, or, if present, are not distinguishable from the sidelobe(s) of the second peak, the one or more parameter(s) are estimated from the second peak. The parameter estimator may be employed in a subscriber station to estimate a parameter such as the time of arrival of one or more base station or sector pilot signals in a wireless communication system. This information may be utilized in an overall advanced forward link trilateration process for estimating the location of the subscriber station.

Abstract: A method for assigning tracking elements includes sorting a list of potential assignments according to a diversity criterion. In one example, a list of received signal instances is sorted first according to a measure of energy and then sorted again according to the diversity criterion. In a further embodiment, a demodulation element may be labeled available for assignment yet continue to output demodulated symbols in a locked state. Applications to a mobile station of a CDMA system for cellular telephony are discussed.

Abstract: A system and method are disclosed by which the effects of time of arrival errors may be reduced. In a mobile unit, such as a CDMA device, a correlation pulse is generated when a transmitted code matches a stored reference code. In the absence of multipath effects, correlation pulses are generated in response to the detection of multiple transmissions of the reference code from multiple transmitters. However, multipath effects distort the generated correlation pulses leading to errors in the time of arrival measurements. The present invention calculates the width of the correlation pulses and determines a delay correction factor based on the pulse width. The delay correction factor is added to the measured delay time to provide a more accurate delay time, thus permitting more accurate location measurements based on time of arrival. In alternative embodiments, other signal factors may also be used to apply delay correction factors. The actual location determination may be performed by the mobile unit, or any other positioning determining entity (PDE). The system is also capable of applying correction factors to time of arrival signals received from global positioning system (GPS) satellites.

Abstract: Techniques for efficiently performing system search to obtain service from a wireless system as quickly as possible are described. A terminal initially looks for service from a first (e.g., W-CDMA) system. The terminal identifies network(s) in the first system from which service was received in the past and performs acquisition on each network to look for service. If service is not found for the first system, then the terminal performs a search for a second (e.g., GSM) system. If service is found on the second system, then the terminal obtains service from the second system and avoids a frequency scan for the first system. Otherwise, the terminal performs a frequency scan for the first system using the search results for the second system. The terminal may obtain a list of RF channels detected for the second system and may omit these RF channels and possibly some other RF channels around these RF channels from the frequency scan.

Abstract: The reliability of transmit power control (TPC) commands received from a transmitter is determined based on a TPC target value. The TPC target value is derived based on a TPC threshold and possibly a weight, depending on the receiver implementation. A received TPC command is considered reliable if its absolute value exceeds the TPC target value. Received TPC commands deemed as unreliable are discarded and not used for power control. Multiple TPC target values, used for detecting UP and DOWN commands, may be derived with multiple scaling factors. For a receiver in soft handover and receiving TPC commands from multiple transmitters, a different TPC target value may be derived for each transmitter. The received TPC commands for each transmitter are compared against that transmitter's TPC target value. Received TPC commands deemed as unreliable are discarded and not combined.

Abstract translation: 基于TPC目标值确定从发射机接收的发射功率控制（TPC）命令的可靠性。 TPC目标值基于TPC阈值和可能的权重导出，这取决于接收机实现。 如果接收到的TPC命令的绝对值超过TPC目标值，则认为它是可靠的。 被认为不可靠的TPC命令被丢弃，不用于功率控制。 用于检测UP和DOWN命令的多个TPC目标值可以用多个缩放因子导出。 对于软切换中的接收机和从多个发射机接收TPC命令，可以为每个发射机导出不同的TPC目标值。 每个发射机接收的TPC命令与该发射机的TPC目标值进行比较。 被认为不可靠的TPC命令被丢弃并不组合。

Abstract: A system and method are disclosed by which the effects of time of arrival (TOA) errors may be reduced. In a mobile unit, a correlation pulse is generated when a signal transmitted from a base station is detected. The transmitted signal may be reflected or defracted such that multipath signals arrive at the mobile unit. This leads to a distortion in the generated correlation pulse and errors in accurate (TOA) measurements. The present invention models the response function and calculates the width of the pulse using the modeling function with a dynamically adjustable factor to indicate at what point down from the peak the pulse width will be calculated. Based on the calculation of pulse width, a type of multipath signal may be determined and an appropriate correction factor applied to the measured (TOA) to provide a more accurate (TOA) determination. The system may apply correction factors to (TOA) signals from base stations in a mobile telephone unit or from signals received from global positioning system (GPS) satellites.
