FIELD: radio communication, discrete information transmission systems using complex wideland signals.
SUBSTANCE: the detector has four multipliers, π/2 - phase shifters, two delay circuits for signal element length, inverter, three adders, two matched filters, two squarers and a threshold device.
EFFECT: provided detection of complex signals with an unknown carrier frequency, preset band of admissible values, and a random initial phase.
