Hi
Your amplitude is set in constellation object, in the
constellation points list.
At present yours is +-1 for BPSK, and +-1+-j for QPSK
So amplitude is 1 (+-1) for BPSK and 1.414 for QPSK
This must be adjusted to your requirements (-0.5,0.5) for BPSK

Hello there, I am working on generating a baseband
signal by using GNU-Radio. I have chosen a random signal along
with the constellation modulator and constellation object.
However, I go through all settings for these blocks but don't
find the setting option for signal 'Amplitude'. How can I be
sure that my generating amplitude (let say peak to peak)?
I can see the signal amplitude in QT GUI Time Sink but I am
not sure how its amplitude define here in this scheme. It
seems like signal amplitude is 2v peak to peak. Is it right?
But I want to generate a baseband signal which will have 1v
peak to peak. Thank you.
