Abstract: The invention relates to a position-adaptive communication method which is carried out by a communication control module of a movable vehicle (1) in order to establish and maintain a communication connection (4) between the vehicle (1) and an opposite station (3). The communication method is a packet-based communication method, and a transmission pause (13) is provided between data packets and/or within the data packets. Position data of the vehicle (1) relative to a global coordinate system is ascertained, and a movement data set is received trout at least one opposite station by means of a receiving device. Position data is extracted from the received movement data, and the position of the opposite station in the global coordinate system is determined. A directional vector (8) front the vehicle (1) to the opposite station (6) is ascertained, and a signal propagation time is ascertained from the length of the directional vector (8). The transmission path (13) is then adaptively matched to the ascertained signal propagation time by a timer of the communication control module.

Abstract: The disclosure relates to a method for monitoring a motion of a subject, as well as to a corresponding system and computer program product. As part of the method, a monitoring signal is emitted towards a corresponding receiver. The motion of the subject is then detected based on a change in the received monitoring signal. Therein, the monitoring signal is emitted using a spread-spectrum technique and/or using an M-to-N and multi-antenna emitter-receiver system with a set of M transmitting antennas and a set of N receiving antennas.

Abstract: A method for estimating arrival time based on noise cancellation, includes transmitting, with a transmit terminal, an ultra-wideband pulse sequence; performing power sampling on a received ultra-wideband signal; averaging a power sampling sequence; carrying out a calculation to obtain a noise mean vector; using a sum-of-rank method to obtain a rank of a power mean column vector; setting a decision threshold; and performing time-of-arrival (TOA) estimation.

Abstract: A method includes transmitting a first electromagnetic signal from a first node to a second node through free space. The method also includes transmitting a second electromagnetic signal from the first node to the second node through a communication link, where the communication link physically couples the first and second nodes. The method further includes identifying a distance between the first and second nodes based on a time-difference-of-arrival between reception of the first electromagnetic signal at the second node and reception of the second electromagnetic signal at the second node.

Abstract: Disclosed are examples of systems, apparatus, methods and computer program products for locating unmanned aerial vehicles (UAVs). A region of airspace may be scanned with two scanning apparatuses. Each scanning apparatus may include one or more directional Radio Frequency (RF) antennae. The two scanning apparatuses may have different locations. Radio frequency signals emitted by a UAV can be received at each of the two scanning apparatuses. The received radio frequency signals can be processed to determine a first location of the UAV.
