Latest Patents

Ciarán's latest patents include a receiver designed for use in an ultra-wideband communication system. This invention involves periodically digitizing a received UWB signal as a series of ternary samples. During the carrier acquisition mode, these samples are correlated with a predetermined preamble sequence to develop a correlation value. When this value exceeds a predetermined threshold, it indicates that the preamble sequence is being received, allowing for the development of estimates of the channel impulse response (CIR). Upon detecting a start-of-frame delimiter (SFD), the best CIR estimate is provided to a channel matched filter (CMF). In the data recovery mode, the CMF effectively filters channel-injected noise from the sample stream. Additionally, both carrier phase errors and data timing errors are continuously detected and corrected during both operational modes.

Another notable patent involves determining the angle of arrival using a reduced number of receivers. This method also utilizes the correlation of received UWB signals and the estimation of the CIR. By comparing the carrier phases of two receivers separated by a known distance, the angle of incidence of the signal can be accurately determined. This innovation allows for the adaptation of one or more receivers to use multiple antennae, thereby reducing the total number of receivers needed.
