The purpose of this thesis is to develop a wireless communication transceiver system compatible with the AX.25/KISS communication protocol using the UHF/VHF cubic satellite wireless communication system development platform [1], and design the overall system modularization.
The system planning mentioned in the paper includes freely setting the carrier center frequency, the amplification power of the power amplifier, and the station call sign. Design automatic packet, automatic unpacking, automatic forwarding and other systems, and the functional block, state machine, after the specific implementation, to achieve a radio transceiver that meets the amateur radio specifications.
And experimentally test the communication compatibility between the transceiver system and the commercially available amateur radio equipment, the reliability of the AX.25 forwarding mechanism, and whether the transmission of the AX.25 communication protocol packet using the KISS communication protocol is successful. Finally, the shortcomings and improvement methods are discussed according to the results.
