Patent number: 11921185Abstract: An ultra-wideband (“UWB”) communication system comprising a transmitter and a receiver having two antennas. An UWB signal transmitted by the transmitter is received at each of the antennas. By comparing the carrier phases of the received signals, the phase difference can be determined. From this phase difference and the known distance, d, between the antennas, the Cartesian (x, y) location of the transmitter relative to the receiver can be directly determined.Type: GrantFiled: July 1, 2022Date of Patent: March 5, 2024Assignee: DecaWave, Ltd.Inventors: Michael McLaughlin, Gavin Marrow, Igor Dotlic

Publication number: 20230300005Abstract: Systems and methods for channel estimation are disclosed. In one aspect, supercomplementary sets (SCSs) of sequences are defined and more optionally, but more particularly, supercomplementary zero-sum cross-correlation (SZC) sequence blocks are created from the SCSs and transmitted to a receiver. The receiver receives a signal that includes the SCSs or SZC sequence block(s) deformed by a channel frequency offset (CFO). The receiver may correlate the signal with the known SCS or SZC to create a signal with minimal or no side lobes from which the CFO may be removed and a channel estimate formed. Based on the channel estimate, a distance between transmitter and receiver may be determined and used for other purposes, such as the provision of location-based services.Type: ApplicationFiled: February 16, 2023Publication date: September 21, 2023Inventors: Igor Dotlic, Ciaran McElroy, Michael McLaughlin

Patent number: 11128058Abstract: An antenna array (10) for detecting an incoming radio wave (52) having an operating wavelength, comprising: a plurality of antenna elements (12) arranged in an array with a periodic repetition of the antenna elements (12). Each antenna element (12) comprises a slot (32) being shaped such that the polarisation of the corresponding antenna element (12) is non-linear, and having a first axis (A1) and a second axis (A2) orthogonal to the first axis. Each of the first and second axes (A1; A2) has a length in the range of about 0.05-0.2 times the operating wavelength of the incoming radio wave (52) and the ratio of the length of the first axis A1 to the length of the second axis A2 is between about 1-2.5. There is also a method of configuring an antenna array 10 for detecting an incoming radio wave (52), and a method of determining the angle of arrival of a radio wave (52) impinging on such an antenna array (10).Type: GrantFiled: June 22, 2018Date of Patent: September 21, 2021Assignee: Decawave, Ltd.Inventors: Igor Dotlic, Giuseppe Ruvio, Jeff Clancy

Patent number: 10673555Abstract: In an ultra-wideband (“UWB”) communication system comprising a pair of UWB transceivers, methods for securely performing channel sounding. In a first GCP Sync method, a pre-determined set of Golay Complementary Pairs is added to an 802.15.4a frame. In a second CLASS method, a cyphered low auto-correlation sum set is added to frame. In a third LCSSS method, a low cross-correlation sidelobe sum set is added to the frame. In general, these methods are adapted to transmit a pseudo-randomly generated codeset which may have inherent sidelobe distortions, and then, in the receiver, to compensate for this, and any channel-induced, distortion by selectively modifing the cross-correlation codeset.Type: GrantFiled: July 23, 2018Date of Patent: June 2, 2020Assignee: DecaWave, Ltd.Inventors: Ciaran McElroy, Jaroslaw Niewczas, Michael McLaughlin, Igor Dotlic, Marcas O'Duinn, Dries Neirynck
