ADAPTIVE DEVICE FOR SEPARATING BINARY PHASE KEYING SIGNALS Russian patent published in 2003 - IPC

FIELD: radio engineering. SUBSTANCE: device that can be used, for example, in radio receivers of multichannel digital communication lines and multiple access networks as well as in digital radio broadcasting and digital television has reference-wave shaping unit 1, three multipliers 2, 4, 16, two low-frequency filters 3, 5, three limiters 6, 10, 11, compensating structure shaping unit 12, three adders 13, 14, 15, and three decision taking units 7, 8, 9. Device functions to divide three linear-dependent binary phase keying signals and incorporates means for reducing loss of noise immunity that may occur due to probable deviations of separation algorithm parameters from optimal values in hardware implementation. EFFECT: enhanced quality of signal separation; improved noise immunity. 3 cl, 3 dwg
