DEVICE FOR DETERMINING HARDWARE TRANSMITTER OUTPUT SIGNAL DELAY Russian patent published in 2016 - IPC H04L25/03 H04B1/04

Abstract RU 2581767 C1

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and can be used in transmitters of a global navigation satellite system signals. Device for determining hardware delay of output signal of the transmitter has a modulation sequence readings, digital-analogue converter, a modulator, power amplifier, a directional coupler, an antenna-feeder unit, analogue-to-digital converter, digital processing unit, a passive frequency-independent Adder, a low-pass filter, the digital processing unit contains filter controlled signal, filter of the reference signal, unit for determining the phase of the reference signal, a comparator unit phases, correlation unit.

EFFECT: technical result-possibility of operation with pseudo noise phase modulated signals with simultaneous increase of accuracy of determining hardware transmitter output signal delay.
