FIELD: physics, communications.
SUBSTANCE: invention relates to radio systems for transmitting discrete data and can be used for no-coherent reception and element-by-element processing phase-shift keyed binary signals. The device has a band-pass filter, a local generator, a phase shifter bank, N reception and processing channels, each of which includes a signal multiplier, a low-pass filter, a clipper-limiter, a decoder, a modulus calculating device and a threshold device, an OR logic element.
EFFECT: possibility of achieving maximum possible noise-immunity of a system with unknown initial phase of the received radiofrequency signal.
