SIGNAL RECEIVING DEVICE USING PSEUDORANDOM OPERATING FREQUENCY CONTROL Russian patent published in 2003 - IPC

Abstract RU 2210861 C1

FIELD: radio engineering; communication systems using pseudorandom operating frequency control. SUBSTANCE: second, third, and fourth band filters, second and third multipliers, pulse noise blanking unit, attenuator, first and second subtracters, limiter, synchro-phase filter, first, second, third, and fourth delay circuits newly introduced in device have made it possible to generate estimate of narrow-band noise followed by its correction using estimate obtained with the result that information characters transferred at frequencies suffering narrow-band noise are not distorted. EFFECT: enhanced immunity to narrow-band noise. 1 cl, 2 dwg
