VHF/UHF-band broadband high-speed data transmission platform

The invention discloses a VHF/UHF (Very High Frequency/Ultra High Frequency)-band broadband high-speed data transmission platform, comprising a power amplification and wave filter module, a radio frequency channel module and a digital signal processing module, wherein the radio frequency channel module firstly converts a radio frequency signal into a medium frequency signal, then performs sampling on the medium frequency signal, and converts the medium frequency signal into the digital signal and sends the digital signal to the digital signal processing module. Medium frequency bandwidth (the medium frequency bandwidth can be adjusted within a range from 25KHz to 8MHz) is dynamically adjusted by utilizing software radio technology in accordance with different application requirements, communication environments and user requirements. The platform runs traditional narrowband low-speed waveform on condition of narrowband medium frequency bandwidth in order to achieve the interconnection and intercommunication with traditional radio, and runs broadband high-speed waveform on condition of broadband medium frequency bandwidth in order to accomplish large-capacity high-speed data transmission. The broadband high-speed data transmission platform can support a plurality of waveforms and operating modes, and meets the demands of broadband high-speed data transmission within a frequency range from 30MHz to 512MHz.
