A communication device includes: a wireless communication section configured to wirelessly receive a signal from another communication device; and a control section configured to, in the case where the other communication device transmits a first signal that includes one or more preamble symbols including one or more pulses, acquire a correlation computation result including a correlation value indicating magnitude of correlation between the first signal and a second signal corresponding to the first signal received by the wireless communication section, as an element obtained at each delay time that is time elapsed after the other communication device transmits the preamble symbol at a designated interval, detect a specific element that is a plurality of the elements included in the correlation computation result, in accordance with a predetermined standard, and calculate a reliability parameter that is an indicator indicating whether the detected specific element is appropriate for a processing target.

Methods, systems, and apparatuses are presented to transmit fragmented communication frames, such as fragmented ultra-wideband (UWB) frames. In some implementations, a communication frame may be divided into a plurality of fragments, and the fragments may be transmitted across a plurality of regulatory test intervals. E.g., each fragment may be transmitted within a mutually-exclusive regulatory test interval. In some implementations, each fragment may be constrained in time and/or transmission power, such that the total energy emitted during transmission of the fragment remains within a maximum energy limit defined for the regulatory test interval, e.g., by a regulatory entity. In some implementations, the sum of the energy emitted during transmission of two or more fragments may exceed the maximum energy limit defined for the regulatory test interval.

A communication method includes generating at a first node, a message of a predetermined message temporal length that indicates an input value to be encoded and transmitting, at the first node, a signal including a pulse train corresponding to the generated message. The signal including the pulse train includes two pulses that define start and end of the message, respectively, and further two pulses that define within the message, a first time interval calculated from the input value in accordance with a first function and a second time interval calculated from the input value in accordance with a second function, respectively.

Disclosed herein are systems and methods related to a wireless tracking system: The wireless tracking system having a plurality of beacons, each of the plurality of beacons having at least one antenna and at least one power source. When the at least one antenna is supplied with power via the power source, a local ping is transmitted from the beacon. A wireless tracking device then receives the ping via its own antenna. Once the wireless tracking device has received a locational ping from at least two of the plurality of beacons, it can then calculate a direct connection path between the at least to beacons. Based on this known path, the wireless tracking device can then determine a distance between the wireless tracking device and connection path. Based on the determined distance, the wireless tracking device may then issue a corrective measure.

A method for high data rate transmission using minimum energy coding with Ultra Wide Band modulation includes encoding each of a plurality of sourcewords into a respective codeword. Each respective codeword includes a single logic-high bit. A codeword duty cycle is less than a low duty cycle threshold, wherein the codeword duty cycle is based on a bit length of the codeword. Each respective codeword is modulated with an On-Off-Keying (OOK) modulation to form a respective modulated codeword, wherein a transmission of each modulated codeword occurs only for the single logic-high bit in each respective codeword.

Wireless digital communication method for the communication between two electronic devices (3, 16) of an industrial apparatus (1), including—encoding each bit of information by a respective sequence of a certain number (N) of pulses (25) that alternate with a corresponding number (N−1) of silence intervals (26), each pulse having a pulse duration (TI) shorter than or equal to ns and said silence intervals having respective silence durations (TSj) longer than or equal to 30 ns—transmitting, by a first electronic device, a radio signal (RS) comprising a plurality of radio pulses corresponding to the sequence of pulses without modulating any radio carrier, and—receiving and decoding, by the other electronic device, said radio signal to obtain said bit of information. The method may include additional steps for exchanging information between the electronic devices according to which one of the electronic devices, while in a stand-by state, transmits a request message, waits for a reply message from the other electronic device (if and when some conditions are complied with) and, upon receiving the reply message, switches to an operating state in which the two electronic devices are communicatively coupled to each other.
