Evaluation of microcontroller based packet radio modem

[摘要] The use of emerging microprocessors has become increasingly popular in packet radio communicationequipment. This is mainly because of the improved performance and hardware simplicitythey offer. The new generation field programmable gate arrays (FPGAs) and microcontrollersare now widely used in the development of terminal node controller (TNC) components.The aim of this thesis is to evaluate the use of these new generation FPGAs and microcontrollersin a TNC design, in order to utilise the software flexibility and hardware simplicity. Thedesign process began with the selection of the available simple microcontroller-based modemthat was just designed. Prior to its usage in a TNC, the software of the modem was modelled,in order to understand its signal processing functionality.
