M-ary Phase Shift Keying demodulator Block
This M-PSK demodulator takes in input two [I;Q] (respectively [u1;u2]) components (real values) and computes a symbol number (integer value) in accordance with the M-PSK modulator block.
The phase is evaluated with the equation :
and the block computes the output integer value with the formula:
where M is the number of states.
- Number of states
The number of state of the modulation.
Type 'vec' de taille 1.
- Inherit (no:0, yes:1)
Herits events by its regular input ports (disable the event input port).
