Receiver for use in an ultra-wideband communication system |
摘要 |
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, 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.
