METHOD FOR FASTER SEARCH OF BROADBAND SIGNALS AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2014 - IPC H04L7/08 G06F17/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to data processing methods and devices in broadband radio communication and radio navigation. The search method involves: parallel accumulation, from the output of dynamically tuned matched filters, of values of a partial periodic cross-correlation function of segments of a received signal with two reference generating lines from which a derived sequence was generated, and determining numbers of cycles of the mutual shift thereof corresponding to delay synchronism; extrapolating the structure of partial periodic cross-correlation functions in form of extrapolation functions of subchannels of two processing channels with two-factor control of extrapolation based on a majority principle; controlling establishment of delay synchronism without determining the current time delay of the received signal and based on the combination of numbers of cycles of synchronism with the generating lines. The dynamically tuned matched filters used in the search channels are acousto-electronic convolvers.

EFFECT: reducing time spent on searching broadband signals based on delay.
