DEVICE FOR RECEIVING AND TRANSMITTING PHASE-KEYED CODE SIGNALS Russian patent published in 2004 - IPC

FIELD: systems for data transfer by noise-like orthogonal codes with phase-keyed modulation of carrier frequency.

SUBSTANCE: proposed device designed to shape rather long phase-coded signals in asynchronous mode of signal transmission by a number of transceivers operating in one channel and to process them at considerable detuning of transceiver carrier frequencies on sending and receiving ends has reverse exchange unit 1, multichannel incoherent correlator 2, multichannel integrator 3, decision unit 4, input/output unit 5, incoherent demodulators unit 6, reference signal generator 7, binary quantizer 8, incoherent matched filter 9 for logically converted code, incoherent matched filter 10 for balance code, adder 11, differentiating unit 12, threshold unit 13, matching unit 14, balance code generator 15, exchange unit 16, logic conversion unit 17, switching unit 18, phase modulator 19, amplifier 20, pulse generator 21, phase shifter 22, control signal shaper 23, and random delay unit 24.

EFFECT: enhanced effectiveness of processing long phase-coded signals at carrier detuning of transceivers on sending and receiving ends.
