DEVICE FOR GENERATION AND PROCESSING OF BROADBAND SIGNALS Russian patent published in 2019 - IPC H04J13/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to noise-protected radio communication systems using noise-like phase-shift keyed signals and can be used in interference-free radio communication systems. Device for generation and processing of broadband signals includes forming and processing parts. Shaping part of the device includes two identical channels containing an encoder, a serial-parallel converter, an M-sequence generator and two modulators. Besides, the forming part of the device contains: a chip frequency generator, a PSP generator, a carrier frequency generator, a phase shifter through 90° and a summing amplifier. Processing part includes two identical channels containing a unit for combining quadratures, a maximum selection unit, a parallel-serial converter, a decoder and two identical sub-channels comprising a multiplier, a readout unit and a Walsh transform unit. Besides, the processing part of the device comprises: an amplifier, an analogue-to-digital conversion unit having two versions, two decimation registers, a sampling frequency generator, a PSP generator and a search and synchronization unit.

EFFECT: possibility to generate and process signals, volume of alphabet and base of which are measured in thousands of units.
