BROADBAND SIGNAL RECEIVING UNIT Russian patent published in 2022 - IPC H04B1/10 H04B7/00 

FIELD: radio engineering and communication.

SUBSTANCE: invention relates to the field of radio communication using broadband phase-shift keyed signals based on pseudorandom sequences (PRS), and can be used in broadband noise-immune radio communication systems. Receiving device of broadband signals comprises series-connected receiving unit (1), analogue-to-digital converter (ADC) (4) and digital receiving unit (DRU) (2), as well as series-connected reference oscillator (7) and clock rate synthesizer (CRS) (5), digital computational synthesizer (DCS) (8). Output of CRS (5) is connected to the second input of ADC (4). Second output of reference generator (7) is connected to the second input of receiving unit (1). Third input of receiving unit (1) is connected to the second output of control unit (6). Third output of control unit (6) is the output of the device, and the fourth output is connected to the third input of DRU (2). Output of the correlation receiving unit (CRU) (3) is connected to the fourth input of DRU (2). Group of inputs/outputs of control unit (6) is connected by bus to group of inputs/outputs of CRU (3) respectively. First input of receiving unit (1) is the input of the device. One input of DCS (8) is connected to output of CRS (5), and the other one is connected to the first output of control unit (6). Decimator (9) is connected between the output of DRU (2) and the first input of CRU (3). DCS output (8) is connected to the second inputs of DRU (2), decimator (9) and CRU (3).

EFFECT: elimination of restrictions on the allowable range of clock rate variation, as well as on the selection of the intermediate frequency in the receiving unit, which ultimately expands the capabilities of digital processing of a complex signal.
