Generic symbol modulator block
That block is a generic symbols modulator.
Arbitrary constellations can be realized by setting
the dialog parameter 'Points constellation' with
a vector of complex numbers.
Demodulation can be done with the pair block
DEMODGEN_c.
- Points constellation
This parameter set the values of symbols in the map I/Q. The used vector can be a vector of complex number of size [1 m], where m is the number of symbols or it can be a vector of real of size [2 m], first row for the value of the I axis and the second for the value on the Q axis.
Properties : Type 'vec' of size -1.
- Inherit (no:0, yes:1)
Herits events by its regular input ports (disable the event input port).
Properties : Type 'vec' of size 1.
