GENERATOR OF PSEUDORANDOM BINARY SEQUENCES

摘要

FIELD: radio engineering.;SUBSTANCE: device includes shift register consisting of n in-series connected quaternary memory cells, where n - odd number; each of the above cells consists of two binary memory cells, initial setup unit, half adder, square wave generator, which forms the sequences of "zero" and "one" signals, feedback unit performing locic operation of multiplication and summing above the contents of memory cells for formation of feedback signal according to characteristic polynomial, bit synchronisation device, devices providing the storage of coefficients of characteristic polynomial and serving as multipliers when performing multiplying operations in feedback unit.;EFFECT: larger volume of group of pseudorandom binary sequences with the same correlation characteristics as in the prototype.;2 dwg
