PI/4 - QPSK (2)

Sets the modulation type to pi/4 QPSK. In this modulation, each QPSK symbol is rotated by pi/4.

PI/8 - 8PSK (3)

Sets the modulation type to pi/8-8 PSK. In this modulation, each 8 PSK symbol is rotated by pi/8.

3*PI/8 - 8PSK (4)

Sets the modulation type to 3*pi/8-8 PSK. In this modulation, each 8 PSK symbol is rotated by 3*pi/8.
