DEVICE OF THE THIRD CRITICAL SCHEME OF ACCELERATED SEARCH AND EFFECTIVE RECEPTION OF BROADBAND SIGNALS Russian patent published in 2022 - IPC H04L7/10 H04B1/10 

FIELD: radio communication.

SUBSTANCE: invention relates to data processing and decision-making devices in broadband radio communication and radio navigation. A device is proposed, in the structure of which a search and detection stage is performed, at which a primary accumulation sub-stage is performed: parallel accumulation from the output of dynamically tunable matched filters of values of segments of the received signal with two reference generating lines, from which a delay search for signals manipulated by derivative nonlinear recursive sequences (NRS) is formed, as well as the determination of clock numbers of their mutual shift corresponding to delay synchronism; an extrapolation sub-stage in the form of extrapolation functions of subchannels of two processing channels with two-factor control of extrapolation according to the majority principle; a synchronization stage with control of establishing delay synchronism without determining the current time delay of the received signal, but based on a combination of synchronism clock numbers with producing lines; a stage of effective coherent reception and decision-making in the “analog single mode of single-channel decision and reception” and with the “discrete final single-channel method” of decision-making with a parallel mode of “synchronization control and correction” without stopping the process of receiving and processing of signals with spectrum expansion (hereinafter – SSE). The device consists of two simultaneously operating and identical processing channels (PC-1 and PC-2) and a synchronism control circuit and a derivative signal generator common to these channels.

EFFECT: increase in the reliability of reception and processing of SSE and decision-making.
