Hi,
that would be called "OOK", on-off-keying, usually, because 0·3 = 0; it has very low
spectral efficiency. Its constellation points would hence be 0 and 3, so the argument to
the constellation object would be [0, 3].
Do note that by default, SDR frontend drivers are configured to map numbers with magnitude
1 to maximum DAC output; you using 3 does sound a bit questionable here, unless you use
that constellation then in a different more complex system and adjust the amplitude of the
result.
Best regards,
Marcus

Hi.
I was wondering what would the parameters of the constellation object be if I am doing
ASK modulation by multiplying each bit with a constant 3?
