FIELD: radio engineering and communications.
SUBSTANCE: invention relates to systems for transmitting information over a radio channel and can be used in constructing executive devices (ED) of command control radio lines (CCRL) operating with binary phase-shift keying signals. When implementing the method of receiving frequency-stabilized binary phase manipulation signals in an unknown initial phase, a three-channel system for receiving frequency-stabilized binary phase-shift keyed signals is used, where signals of reference generators of each of channels have phase shift equal to π/3, relative to each other and operation of threshold devices in each of three channels is organized in direct and inverse mode. Power loss of the proposed device compared to the scheme of ideal synchronization of receiving the phase-shift keyed signal will make about 0.45 dB (by power), which is acceptable. Device for receiving frequency-stabilized signals with binary phase-shift keying at unknown initial phase contains analogue-to-digital converter of ADC 1, digital matched filter of DMF 2, a unit for storing code combinations USCC 8, a logical element OR 11 and three identical signal processing channels, each of which consists of a multiplier of signals MP 3, a reference generator G 4, a low-pass filter LPF 5, amplitude limiter AL 6, comparison circuit CC 7, integrator INT 9 and threshold device TD 10. Urgency of reducing hardware costs is determined by the need to implement ED CCRL in an autonomous version with minimum current consumption.
EFFECT: significant (almost fivefold) reduction of hardware costs when implementing a scheme for receiving frequency-stabilized signals with binary phase-shift keying at unknown initial phase.
