Patent number: 10090879Abstract: In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. The samples are continuously correlated with a predetermined preamble sequence to develop a correlation value. When the value exceeds a predetermined threshold, indicating that the preamble sequence is being received, a stream of estimates of the channel impulse response (“CIR”) are developed. When a start-of-frame delimiter (“SFD”) is detected, the best CIR estimate is provided to a channel matched filter (“CMF”) substantially to filter channel-injected noise. The time of arrival of the first arriving path is developed from the stream of CIR estimates.Type: GrantFiled: November 10, 2014Date of Patent: October 2, 2018Assignee: Decawave, Ltd.Inventors: Michael McLaughlin, Billy Verso, Tony Proudfoot
