    Abstract: 모바일디바이스들은종종, 네트워크내의모바일디바이스들의포지션정보를계산하기위해 OFDM(orthogonal frequency division multiplexing)을사용한다. 그러나, 포지셔닝을위한모바일디바이스와신호소스사이의물리적거리및 다른환경요인들은수신되는신호들의신호강도에영향을미칠수 있다. 모바일디바이스에서수신되는더 강한신호들은, 특히 2개의신호소스들이동일한심볼을점유할때 더약한신호들이묻히게(drown out) 할수 있다. 종래의 OFDM에서, 신호소스는각각의포지셔닝기회(positioning occasion)에대해동일한심볼을송신하므로, 더약한신호는더 강한신호에비해절대검출되지않을수 있어서, 포지셔닝계산들의정확도가감소된다. 신호소스로부터의더 약한신호가포지셔닝기회들중 적어도일부에서검출될수 있도록, 무선네트워크의각각의신호소스에대해지정된심볼을변경하기위해패턴을사용하기위한시스템들및 방법들이본원에서설명된다.

    Abstract: Mobile devices often use orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, physical distance between the mobile device and a signal source for positioning and other environmental factors can influence the signal strength of received signals. Received signals at the mobile device that are stronger may drown out the weaker signals, particularly when two signal sources occupy the same symbol. In traditional OFDM, a signal source transmits the same symbol for each positioning occasion, so a weaker signal may never be detected over a stronger signal, reducing the accuracy of the positioning calculations. Described herein are systems and methods for using a pattern to vary the designated symbol for each signal source in a wireless network so that a weaker signal from a signal source may be detected on at least some of the positioning occasions.

    Abstract: A mobile communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.
