摘要： Implementations relate to systems and methods for generating compensated speed values for a Doppler-enabled device. A portable wireless device can contain a GPS navigation engine (110) to capture position data (120) and Doppler speed data (118) from positioning satellites. The device can also generate position-based speed values from successive position readings and time intervals, to determine the current speed independently of the Doppler-based speed values. During degraded signal conditions, the Doppler-based speed values can drop to invalid levels. The device incorporates a combiner module (450) which compares the position-based and Doppler-based speed values and performs combination operations on those quantities to produce a compensated speed value (490). By selecting the maximum or otherwise combining those values, extreme excursions in speed values are avoided and accuracy promoted.

摘要： The invention relates to a method for determining the distance between a radio beacon and a vehicle device passing in front of said radio beacon, in a road toll system. A signal of a frequency having a known temporal profile is emitted. Said method consists of the following steps: the signal is captured in the other component when passing and the temporal profile of the frequency is recorded in relation to the known temporal profile; a modification in the recorded frequency profile exceeding a first threshold value is detected; two distant wave zones in the frequency profile, lying temporally in front of and behind the detected modification, which displays a frequency modification below a second threshold value, are searched for; the recorded frequency profile is scaled in such a manner that the distance wave zones take the predetermined values; and said distance “a” from the scaled frequency path is determined. The invention also relates to radio beacons, installations and vehicle devices for implementing the method.

摘要： A system for measuring the radial speed of a moving body in a line of sight determined for a referential position is disclosed. The system includes an emitter assembly for emitting a signal and a referential receiver assembly dedicated to reception of the signal. The emitter assembly is disposed on a first of the elements of a group formed by the moving body and the referential position. The receiver assembly is disposed on a second of the elements of the group. The emitter assembly is able to emit a signal on at least two emission frequencies, where the emission frequencies are separated by a chosen emission frequency gap. The system also includes an analyzer configured to analyze the signal received by the receiver assembly, and to measure the reception frequency gap separating the signal reception frequencies to calculate the radial speed of the moving body according to a function of the reception frequency gap and emission frequency gap.

摘要： A device may include a radio signal receiver, and an inertial navigation system. Additionally, the device may include a processor to determine that the inertial navigation system has been initiated, monitor a radio signal associated with a mobile network received at the radio signal receiver, and determine a channel impulse response (CIR) based on the radio signal. The device may also monitor a Doppler spread of the radio signal based on the CIR in a time domain until a zero Doppler spread is identified. The device may recalibrate the inertial navigation system based on the zero Doppler spread.

摘要： Systems, devices and techniques for wireless communications include receiving a plurality of wireless transmissions over an observation period from a transmitter of a mobile terminal, calculating a plurality of frequency offset values based on the received plurality of wireless transmissions and estimating a speed value based on the plurality frequency offset values. In some implementations, the speed value is determined as a function of a computed frequency offset measurement error. Implementations can be made to include estimating channel characteristics in communication between a base station and the mobile terminal based on the estimated speed and optimizing a property in communications with the mobile terminal based on the estimated channel characteristics. In some implementations, the property can include a modulation scheme or scheduling of transmissions for communications between the base station and the mobile terminal.
