Quasi-optimal grouping for broadcast systems with hierarchical modulation
Hugo Meric, José Piquer, Jérôme Lacan
Recently, we proposed to combine time sharing with hierarchical modulation to increase the transmission rate of broadcast systems. Our proposal involves to group the receivers in p…

Performance Evaluation of Bit Division Multiplexing combined with Non-Uniform QAM
Hugo Meric, Jose Miguel Piquer
Broadcasting systems have to deal with channel variability in order to offer the best spectral efficiency to the receivers. However, the transmission parameters that maximise the s…

DVB-S2 Spectrum Efficiency Improvement with Hierarchical Modulation
Hugo Meric, Jose Miguel Piquer
We study the design of a DVB-S2 system in order to maximise spectrum efficiency. This task is usually challenging due to channel variability. Modern satellite communications system…
