US 12,652,074 B2 · Ultra wideband radio devices and methods

Abstract

Ultra-Wideband (UWB) technology is a wireless technology supporting the transmission of large amounts of digital data over short distances using coded impulses over a wide frequency spectrum with very low power. Enhanced link performance and functionality of such UWB systems is presented exploiting multiple directive antennas for spatially filtering undesired signals and increasing signal strength whilst circuit complexity is reduced by eliminating baluns in prior art solutions. Further enhancements support payloads with flexible encoding schemes, improved channel utilization, reduced processing logic, improved robustness in correlation techniques, versatile synchronisation techniques, improved ranging, as well as providing for improved inter-symbol interference tolerance and detection.

Dependent claims

A method comprising:

providing an ultra wideband (UWB) device;
and
executing a process with respect to the UWB device;
wherein
the UWB device is a UWB receiver forming part of a wireless radio and the process comprises:
receiving a frame of data from another wireless radio upon the wireless radio comprising the UWB receiver;
immediately starting to transmit a preamble of an auto-reply message with the wireless transceiver after receipt of the frame of data;
processing the received frame of data;
determining whether the auto-reply frame should not be sent in dependence upon the processing of the received frame of data;
upon determining the auto-reply frame should not be sent terminating the transmission of the preamble;
and
upon determining the auto-reply frame should be sent continuing to transmit the preamble and the remainder of the auto-replay frame.
