摘要： The present invention relates to detecting the time of the earliest reception of a signal change. In particular, the method according to the invention allows early detection of the signal change, which significantly reduces the timespan available for an undetected relay attack and can thus prevent such an attack or at least make it significantly more difficult, without the data transmission systems that consist of the transmission technology, such as UMTS, LTE, or Bluetooth, having to be modified for this purpose or ultra-wideband signals being required. The object is achieved in that the earliest time at which there is a statistically significant signal change is selected as the time of the earliest reception, wherein the threshold of the statistical significance is determined from the signal itself.

摘要： The invention relates to a method for improving transit time and/or phase measurement and/or for synchronization in digital transmission systems. According to the invention, at least one first, particularly digital, piece of information in at least one first analog signal is transmitted in encoded form between two objects by means of the transmission system and at least one first sample value of the at least one first analog signal is used to determine a temporal position and/or phase relationship. The at least one first sample value lies in a rising or falling edge of the at least one first analog signal and/or of the at least one first received analog signal, which can be recognized, for example, from the sample value itself and/or the characteristic of adjacent sample values.

摘要： A design for secure radio authorization systems in respect of a discovery of an attack on a radio authorization system, in particular for access restriction systems, for example for securing radio keys, for example for automobiles. The design can be used in simpler systems and can be combined with the numerous known solutions, such as complex enabling signals, that, from a design point of view, are not dependent on the assumption of limited computing power. This object is achieved by a design in which the focus is not on the direct prevention of an attack, but rather on a determination of whether or not a signal is an original signal of the radio authorization system, specifically with reference to the signal and not (only) with reference to the content encoded in the signal, by checking whether a metric of the spectral distribution lies within a predetermined range.

摘要： The present invention relates to a process for determining a position change or the resting and/or a speed of an object and a corresponding process for supporting an inertial measurement system. In the process at least one radio signal (FS) is received on the object (O) at at least one first and one second point in time, particularly continuously, and the change of the phase of said radio signal is determined for a determination of a relative movement between source (U) of said signal or a reference location and said object (O), and the relative movement between source (U) of said signal or the reference location and said object (O) is detected.

IPC分类号： G01S13/76
摘要： A method and a system for high-resolution measurement of distance between two objects by means of electromagnetic waves is such that measurements are performed in a reliable, simple, and quick manner with low bandwidth and high accuracy even in complicated multipath environments and/or with moving objects. The method includes determination of a supposed distance and/or supposed relative speed between first and second objects from an object of measurement by comparing the object of measurement with a set of stored and/or calculated reference objects of measurement. The reference objects of measurement relate to different distances and different relative speeds, each reference object being associated with a distance and a speed. The supposed distance and/or speed is assumed to be the distance and/or speed that is associated with the stored and/or calculated reference object of measurement that best fits, is closest to, and/or is most similar to the object of measurement.
