Synchronization method for transmitting reference Chirp ultra- wideband system group based on multiphase filtering code domain

The present invention relates to a synchronization method for transmitting reference Chirp ultra- wideband system group based on multiphase filtering code domain which can solve problem of timing synchronization right modulation for receiving signal in remote distance ultra- wideband communication. The method includes steps as follows: modulating, filtering, multi-signal time-delay accumulating by Chirp-UWB signal and local Chirp-UWB signal, transmitting data to threshold, processing data comparing with the time-delay accumulating data, the data over self-adapt threshold processing multi-path identification, comparing the data obtained by threshold comparative with the multi-path data processed factual for making the signal in enabling state, and keeping follow enabling signal in a close state, adjusting operation clock and local oscillation operation clock, confirming clock adjustment sizes and direction according with equivalent signal radial time delay T value size and completing synchronous tracking.
