Abstract
Устройство синхронизации в системе радиосвязи с псевдослучайной перестройкой рабочей частоты, содержащее опорный генератор, генератор псевдослучайных цифровых последовательностей, устройство управления, отличающееся тем, что в состав изделия введены блок аналого-цифрового преобразователя (АЦП), вход которого является входом устройства, выход АЦП соединен со входом блока «оконной» обработки (БОО) сигналов, выход блока «оконной» обработки сигналов соединен с блоком дискретного преобразования Фурье (ДПФ), выход блока ДПФ соединен со входом блока формирования гипотез о значении величины задержки сигналов по времени и сдвига по частоте (БФГ), выход блока БФГ соединен со входом блока определения глобального максимума (БОГМ), выход блока БОГМ является выходом устройства синхронизации, другие входы БФГ являются выходами генератора ПСП и блока управления, а другие выходы блока управления являются входами блоков АЦП, БОО, ДПФ, а выход ОГ является входом блока управления. A synchronization device in a radio communication system with a pseudo-random tuning of the operating frequency, containing a reference generator, a pseudo-random digital sequence generator, a control device, characterized in that the unit contains an analog-to-digital converter (ADC), the input of which is the input of the device, the ADC output is connected to the input of the window processing unit (BOO) of signals, the output of the window processing of signals is connected to the discrete Fourier transform (DFT), the output of the DFT block is connected to the input the house of the hypothesis formation block about the value of the signal delay time and frequency shift (BFG) value, the BFG block output is connected to the input of the global maximum determining block (BOGM), the BOGM block output is the output of the synchronization device, the other BFG inputs are outputs of the PSP generator and the block control, and other outputs of the control unit are the inputs of the ADC, BOO, DFT units, and the exhaust output is the input of the control unit.
