ADAPTIVE SEPARATOR FOR BINARY PHASE-KEYED SIGNALS Russian patent published in 1999 - IPC

FIELD: radio engineering. SUBSTANCE: device designed, in particular, for multichannel digital communication links and multiple-access networks using power lockout protocols as well as for digital radio broadcasting and digital television has first through sixth multipliers, first through sixth low-frequency filters, first, second, and third reference wave generating units, first, second, and third resolving units, first, second, and third calculators, first, second, and third limiters. Mentioned new combination of essential characteristics provide for separating three generally non-orthogonal binary phase- keyed signals, including linear-dependent ones, such as signals fully identical in shape and differing only in amplitude (power) and in independent data phase inversion on the background of additive white Gaussian noise. EFFECT: improved efficiency of device functioning at desired frequency and power requirement. 7 dwg
