My first step is to add FPGA into the hydroacoustic communication system to improve the performance and anti-interference of the system, the second step is to import the algorithm into FPGA, and the third step is to optimize the algorithm
So first I have to go to add FPGA to hydroacoustic communication system, but I don't have any clue, are there any papers I can refer to?
If you are familiar with FPGA, then I would recommend first to model the system in Matlab eventually, and use a ready made board (big enough fro the project).
Developing your own FPGA board, that is another piece of cake ... That is much difficult problem it is a question of PCB design and simulation also, not only an FPGA design.
