TRACING WIDE-BAND SIGNAL RECEIVER Russian patent published in 2000 - IPC

FIELD: radio engineering. SUBSTANCE: device has seven multipliers (1, 2, 3, 4, 5, 6, 7), four integrators (9, 10, 11, 12), two vector absolute value calculation units (14, 15), subtraction unit (16), code generator shift register (24), quarter phase shifter 23, automatic phase-controlled frequency tuning (8), controlled voltage generator (13), timer (18), decision making unit (17), gate (19), clock oscillator (21), variable rate divider 22, dividing rate control unit (10). Device provides possibility to evaluate static error and compensate it taking into account absolute value of carrier frequency shift. In addition, device provides increased stability of synchronization by 2-4 dB. EFFECT: increased stability and increased precision of establishing synchronization. 4 dwg
