Dear all, I have a question related to the constellation objects in gr-digital. After checking the constellation.cc, I found the constellation of 8PSK and QPSK class are all Grey coded. Now I want to use a 8PSK constellation with natural mapping. I know I can just modify the constellation indexing of the Grey mapped 8PSK class. But I don't want to change the 8psk class that gnuradio provided or to make a natural mapped 8psk class by copying the 8psk class and just modifying the indexing. Is there any clean way to get the natural mapped 8psk class I wanted? Thanks! Best, Zhe -- View this message in context: http://gnuradio.4.n7.nabble.com/Question-on-incorp...

You are perfectly safe setting up your own Constellation Object with whatever constellation and symbol mapping you want. Tom
