Method and the device of the complex decrease in detecting the signature line where delay Doppler movement was done

摘要

The signature line is used in the radio signal on the channel, is detected depending upon reception bureau. The signature line delay in the basic line - selects from gathering in the line which is formed with Doppler movement. When substring gathering is used, for example, to calculate detection metric more efficiently, detection in the signature line is simplified e.g., it becomes easy. As for the sensing station which is simplified, the algebra technology (discrete Fourier transform (DFT) uses the prudent line allotment strategy) whichIt uses. As effective deformation example, concerning the type which has the basic line which can display with the segment of the sine curved line whose length is equal, also it is achievable furthermore to make complexity decrease by using past output again in the succeeding segment which delay - segments Doppler correlation with when overlaps.
