Hi All, I am a second-year Electronic Engineering student with an Individual Project being ~30% of my next (third) year.
For this Individual Project I had the idea of designing a VHF packet stream for Codec2. The general idea is for it to be similar in functionality to D-STAR, but redesigned from the ground up to attempt improvement over D-STAR (particularly in SNR margin), probably still using GMSK though for compatibility. The project would consist mainly of simulation (MATLAB, GNUradio) and comparison of options (modelling 4800 baud + lots of FEC against 2400 baud, differing interleaving intervals with burst QRM, etc), with the plan of conducting software-radio RF real-path testing for validation towards the end of the project. The end result would be a tested and validated protocol specification. No hardware implementation would be designed, leaving that up to the community if they wish and allowing for further development of the Codec2 bitstream to not interfere with the project or vice versa. I am aware there has been significant development on a VHF modem recently, but having already been allocated a relevant Supervisor and received the offer of some fancy equipment, I think I will probably go ahead with this project anyway, just as an academic exercise for myself and some marks on my degree. I'm not looking for any technical input at this stage, I'm still in the middle of Exams so just a heads up. It does look like by the time I actually get started, you guys will already have something finished!
