Abstract :
We present some coded-modulation designs suitable for unequal error protection in digital satellite transmission. Due to the nonlinear nature of the channel, the constellations chosen must have constant envelope, so that signaling schemes derived from PSK should be used. Moreover, the complexity of the design is kept to a minimum
