METHOD FOR THIRD DECISIVE SCHEME OF ACCELERATED SEARCH AND EFFECTIVE RECEPTION OF BROADBAND SIGNALS Russian patent published in 2022 - IPC G06F17/10 H04L7/10 

FIELD: communication.

SUBSTANCE: invention relates to methods for data processing and decision making in broadband radio communication and radio navigation. The method contains: a stage of search and detection, at which a substage of primary accumulation is performed: parallel accumulation from an output of dynamically adjusted coordinated filters of frequency correlation function (hereinafter – FCF) values of received signal segments with two reference production lines, from which a derived non-linear recurrent sequence (hereinafter – DNRS) is formed, as well as determination of numbers of cycles of their mutual shift, corresponding to synchronism with delay; a substage of extrapolation of a structure of FCF, periodic cross-correlation function (hereinafter – PCCF) in the form of extrapolation functions of subchannels of 2 processing channels with 2-factor extrapolation control according to the majority principle; a stage of synchronization with control of establishment of synchronism with delay without determination of the current time delay of the received signal, and with combination of numbers of cycles of synchronism with production lines; a stage of effective coherent reception and decision making in an analogue “single mode of single-channel decision and reception”, and with a discrete “final single-channel” method, decision making with parallel-implemented mode of “control and synchronization adjustment” without stopping a process of reception-processing of spread spectrum signals (hereinafter – SSS).

EFFECT: reduction in time of search by SSS delay, increase in the reliability of reception-processing of SSS on decision making, provision of high structural secrecy and spoofing resistance in all stages of SSS reception-processing.
