METHOD OF THIRD DECISION CIRCUIT FOR ACCELERATED SEARCH AND EFFICIENT RECEPTION OF BROADBAND SIGNALS Russian patent published in 2024 - IPC H04L7/08 

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to methods of data processing and decision making in broadband radio communication and radio navigation. For this purpose, a method is proposed, which includes: a search and detection stage, at which a sub-stage of primary accumulation and a sub-stage of extrapolation of the structure of CCF, PVCF; synchronization stage with control of synchronism establishment by delay without determination of current time delay of received signal, and by combination of synchronism clock numbers with generating lines; stage of effective coherent reception and decision making in "final mode of two-channel decision and reception", based on the use of the resultant total accumulation in 2 channels of receiving the values of the PNP CCF levels for making a decision based on the maximum likelihood criterion, with parallel realized mode of "control and correction of synchronization" without interruption of process of reception-processing of SPS.

EFFECT: reduced time of search by delay of signals with spreading spectrum (SPS), increased reliability of SPS reception-processing, provision of high structural security and imitation resistance.
