A RECEIVER FOR USE IN AN ULTRA-WIDEBAND COMMUNICATION SYSTEM |
摘要 |
<p>In an ultra-wideband ("UWB") receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode of operation, 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 ("OR") are developed. When a start-of-frame delimiter ("SFD") is detected, the best OR estimate is provided to a channel matched filter ("CMF"). During a data recovery mode of operation, 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.</p> |
