This is a small program/simulation/whatever meant to emulate an OFDM modem. This is the pilot work for creating an underwater communications system for ARVP. Eventually I want to put this on an FPGA. (will it fit on an iCE40 I wonder?)
Lot's of credit to dspillustrations.com, the linked post has been super useful to me, and while I try to claim I came up with most of this code myself, it would have taken a LOT longer to do without this post.
I should write stuff down here to help solidify my mental model of OFDM, but for now, you get nothing.
I want this to actually do something at some point, so I want to implement more.
For example, I need to implement something that mimics how a receiver would actually work, where it is unsure of where the packet starts. As well, I want to implement some sort of communications protocol. And figure out how we could easily integrate it with software on the robot.
