Achievable rates optimization for broadcast channels using finite size constellations under transmission constraints

HIGHLIGHTS

• who: R ESEA R CH and colleagues from the superposition modulation increases when the SNR gap between users decreasesWe observed also that superposition modulation outperforms time sharing in a large part of the achievable rate region. On the other hand, it is shown that using the general case of superposition coding can bring important gains compared to classical schemes. We observed also that in the case of finite input alphabet, superposition modulation is not the optimal strategy as in the case of Gaussian input alphabets. Finally, in order to make clear that this paper provides useful tools . . .
