FREQUENCY-KEYED SIGNAL RECEIVER Russian patent published in 2003 - IPC

Abstract RU 2211542 C2

FIELD: radio engineering. SUBSTANCE: novelty is that known device for receiving binary frequency-keyed radio signals with random initial phase which has two matched filters, two envelope separating units, subtracting unit, and threshold unit is provided in addition with digitizer, nonlinear inertialess conversion unit, and adapting unit wherein parameters of nonlinear inertialess conversion unit characteristics are estimated basing on estimation of noise envelope distribution. EFFECT: enhanced signal- to-noise power ratio at receiver output in broadband nongaussian noise environment. 1 cl, 1 dwg
