Video transmission system

System principle:

The video transmission system consists of two upper computers, two USRP-LW N210, and two UBX-LW 40 antennas. At the transmitter end of the system, the upper computer captures the video signal through the camera, and the signal processing software processes the video signal and transmits it to the wireless electromagnetic environment through the USRP-LW N210, UBX-LW 40 and the antenna. At the receiver end, the system receives the wireless electromagnetic signal through the USRP-LW N210, UBX-LW 40 and the antenna. The signal data is processed through the upper computer software, and the recovered video screen is displayed to the upper computer. The two USRP-LW N210 are connected together through the MIMO line for clock synchronization.

System function:

The video transmission system mainly transmits the camera signal data to the wireless electromagnetic environment, and restores and displays the signal data at the receiving end. The system supports a variety of modulation methods, data packets support customization, and the sending source can choose text, pictures and videos. The system receiver can display constellation diagram, spectrum diagram and time domain waveform diagram.

System application:

The video transmission system helps users quickly build a data transmission system, which can be used for antenna performance verification, intelligent metasurface system verification, millimeter wave communication system verification, and photoelectric transmission system performance verification.
