| Feb 21, 2016 at 15:22 | comment | added | Rayne | I got my bit mapping above by looking at the bit mapping of a circular 8-PSK and giving the same code to points at the relative same location. Is there a systematic way of assigning bit mapping to the constellation? For example, if I pick a point to start, are there any rules to let me assign a code to its neighbors? How many different bit mappings in total is there for this constellation? | |
