MULTICHANNEL DIGITAL EXCITATORY SYSTEM Russian patent published in 2019 - IPC H04B7/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering and communication and can be used in radio transmitting equipment. To achieve the technical result, the system is based on a single universal digital FPGA module, which includes different functional units which form coherent signals to provide the desired beam pattern. Control of the module operation mode and delivery of all information required for generation of the emitted signal are carried out through the interface unit over an Ethernet network and processed by a digital signal processor which generates a low-frequency quadrature signal. System implements direct synthesis of a radio frequency and transfer of a low-frequency quadrature signal to a working frequency, and a radio signal generated by digital methods is transmitted to a digital-to-analogue converter.

EFFECT: broader functional capabilities by implementing new modes of operation of promising radio links, improved methods of digital signal generation and noise immunity of radio communication.
