Re: [Discuss-gnuradio] QAM demod Error in GRC

[udadidd]

Hi Josh
I am trying to implement this qam8_demod()
I did not follow this statement that u have mentioned in one of ur previous
mails "you just have to run a packet receiver on each different phase
orientation of the constellation"

Can u plz explain me the same?
I have an understanding that the demod structure follows the same as that of
dqpsk/d8psk.
This is how i see the constellation of the demod

I really need to implement this and need some suggestion on this

Thanks a lot
Udaya

Someone has to invent it. Most of the blocks are there in the d8psk 
demodulator, you just have to run a packet receiver on each different 
phase orientation of the constellation, and pick whichever one gets a 
packet. Ugly solution codewise, perhaps that is why no one has 
implemented it.

I have no idea.
