| description | The invention provides a middle and long distance satellite signal transmission method based on a baseband resource pool, which mainly comprises the following steps of: tracking and receiving a satellite signal by an antenna; a downlink radio frequency signal is subjected to LNA amplification processing at a corresponding frequency band, a 1.2 GHz/70MHz intermediate frequency signal is output through exchange and frequency conversion and enters a signal acquisition device, a high-speed/low-speed digital ADC in the signal acquisition device is used for analog-to-digital conversion and other processing of the signal, and the signal is output to an OTN access device through an optical module. The remote optical transmission channel transmits the digital optical signals back to the central machine room, the digital optical signals are uniformly accessed to the OTN equipment after being transmitted back to the central machine room, and the upper computer management software commands the OTN equipment to complete e |
