Someone made a PWA out of my Android Robot36 SSTV Decoder:

Took a couple of prompts and it still feels not right. Also did some editing as it refused to delete the last redundant frame. Ah well.

Robot36 or Rattlegram wouldn't have existed if I would have sabotaged myself

Successive cancellation decoding is a lot like eating a box of chocolates: If you accidentally choose a very flavorful one somewhere in the middle of the consumption, the rest of the chocolates will taste dull.

Is it just me or are the fscking fireworks getting louder each year?

For PAC codes to work well, we need to abandon the CRC (in favor of a better code-rate) but still can use list decoding. With a list size of just L=64, we come dangerously close to OSD decoding of BCH codes! We also need to replace the Polar code construction (the selection of frozen bits) with something that gives us better distance properties over better polarization properties. Here the Reed Muller based construction comes in handy and is super simple to compute, as you can see in the screenshot.
