DEVICE OF THE THIRD DECISION CIRCUIT OF ACCELERATED SEARCH AND EFFICIENT RECEPTION OF BROADBAND SIGNALS Russian patent published in 2020 - IPC H04L7/08 G06F17/15 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Technical result is achieved due to device of the third decision circuit of accelerated search and efficient reception of broadband signals, containing: two processing channels of correlator type; reference sequence generator; synchronism by delay monitoring circuit; shift computer c₁ and c₂; a unit of digital sub-correlators, each of which contains: acoustic-electronic convolver, amplifier, analogue-to-digital converter; accumulation and extrapolation circuit, which contains for two processing channels along l₁ and l₂ search subchannels; key assembly; accumulator-adder unit; verification unit, which is a two-input AND element block; central digital comparator; unit for selecting subchannel number, including cross-block and delay unit per cycle; search sub-channel; digital parallel adder, wherein the device includes first and second reception and decision channels as receiving parts of the first and second processing channels, comprising first and second units of l₁ and l₂ parallel adders.

EFFECT: technical result consists in faster search and synchronization of signals, as well as higher reliability of receiving-processing derivatives of nonlinear recurrent sequences and making a decision.
