I am manipulating GNU Radio Companion.
Traceback (most recent call last):
File "/users/anb10/metrics/error_rate.py", line 342, in <module>
tb = error_rate()
File "/users/anb10/metrics/error_rate.py", line 225, in __init__
self.digital_constellation_decoder_cb_0 = digital.constellation_decoder_cb(digital.constellation_qpsk)
File "/usr/lib64/python2.6/site-packages/gnuradio/digital/digital_swig.py", line 3096, in constellation_decoder_cb
return _digital_swig.constellation_decoder_cb(*args, **kwargs)
TypeError: in method 'constellation_decoder_cb', argument 1 of type 'digital_constellation_sptr'
I don't know what went wrong. I have even tried digital.psk.psk_constellation(m=4,mod_code='gray'), digital.constellation_8psk and digital.psk.psk_constellation(m=8,mod_code='gray') as a "Constellation Object" argument.
So, what is the proper way to define the argument (Constellation Object) in the "Constellation Decoder" block?
I hope you can give me some ideas. Any help is appreciated. Thank you.
