Abstract:
In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode, 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, 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”). During a data recovery mode, the CMF filters channel-injected noise from the sample stream. Both carrier phase errors and data timing errors are continuously detected and corrected during both the carrier acquisition and data recovery modes of operation.

Claim (Index 6):
The method of  claim 3  wherein step 3.4 is further defined as comprising the steps of:\n 3.4.1. developing a timing phase error as a function of said on-time estimate, a selected early estimate in said second set of estimates preceding said on-time estimate, and a selected late estimate in said second set of estimates following said on-time estimate; \n 3.4.2. filtering the timing phase error as a function of a selected timing loop filter proportional gain and a selected timing loop filter integral gain to develop a filtered timing phase error; and \n 3.4.3. resampling the filtered carrier signal as a function of the filtered timing phase error.
