Diversity Analysis of Hierarchical Modulation in Cooperative Communication
In cooperative communication systems, hierarchical modulation is used to increase systems robustness and to send different information flows simultaneously. In cooperative communication systems which use hierarchical ...
Maximum-Weight Scheduling with Hierarchical Modulation
In this paper, hierarchical modulation is used in conjunction with maximum-weight scheduling to achieve lower transmission delays. Via hierarchical modulation, the scheduled user has the option to transmit to two users ...
