In accordance with a first aspect of the present disclosure, a communication system is provided, comprising: a plurality of communication nodes which are operatively coupled to each other, wherein each of said communication nodes comprises a first radio frequency (RF) communication unit configured to perform ranging sessions with an external communication device; a controller configured to create a logical subset of said communication nodes based on an indication of a channel quality between the communication nodes and the external communication device, wherein said indication of the channel quality has been obtained using a second RF communication unit comprised in each of said communication nodes; the controller further being configured to cause that only the communication nodes included in said logical subset perform said ranging sessions with the external communication device.

Communication system and operating method

There is described a radar system () and a corresponding method, the radar system () comprising i) a control unit (), configured for generating a code (C) comprising a sequence of code symbols (), wherein generating the code (C) comprises randomly selecting a plurality of code symbols () from a code symbol pool () comprising a plurality of code symbols (), ii) a transmitter (), configured for generating a signal (S) from the code (C), and further configured for transmitting the signal (S), iii) a receiver (), configured for receiving an echo (E) of the signal (S), and iii) a correlator (), configured for correlating each code symbol of the code (C') of the received echo (E) of the signal (S) to a corresponding symbol template (R) associated with the correlator (); wherein the radar system () is further configured for synchronizing the symbol template (R) to the code (C) of the signal (S). There is further described a method of using a sequence of randomly selected code symbols () in a radar application, in particular an UWB-based radar application, to prevent replay attacks.

Radar system and a radar method for replay resistant radar operations

There is described a ultra-wide band (UWB) communication device, comprising: Further, a UWB communication system and a method of determining a distance are described.

Ultra-wide band distance determination with an angle-of-arrival based disturbance compensation

In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: an ultra-wideband (UWB) communication unit configured to carry out UWB communication with an external communication device; a plurality of antennas operatively coupled to said UWB communication unit, at least one inertial sensor; an antenna selection unit configured to select, based on an output of the inertial sensor, a specific antenna of said plurality of antennas for carrying out the UWB communication. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication device is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.

Communication device and method of operation

In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: a plurality of antennas; a communication unit configured to execute ranging sessions with an external communication counterpart through said antennas; an antenna selection unit configured to select a specific antenna from said plurality antennas for carrying out one or more of said ranging sessions, wherein the antenna selection unit is configured to select said specific antenna in dependence on one or more parameters indicative of a communication quality between the antennas and the external communication counterpart. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication device is conceived. In accordance with a third aspect of the present disclosure, a computer program is provided for carrying out said method.
