Re: [Discuss-gnuradio] Chunks to symbols with 16 QAM modulation

[Rafik ZITOUNI]

Dear Cinaed, 

Thanks for your answer. 

I tried with my Tx and it works fine with a constellation, but with my receiver symbols or  constellation_decoder, digital.qam_16()[1] gives me an error. 

line 164, in __init__

    self.digital_constellation_decoder_cb_0_0 = digital.constellation_decoder_cb(digital.qam_16()[1])

Best,

Try

 Symbols:        digital.qam_16()[1]
 Constellations: digital.qam_16()[0]
