Abstract :
Coded modulation schemes for hierarchical broadcasting employing multilevel coding (MLC) are considered for both, AWGN and flat Rayleigh fading channels. Design rules for signal constellations and codes are discussed. The superiority of hierarchical schemes based on MLC over time-sharing is shown
