[en] In this paper, we investigate the performance of optimized overlay modulation schemes and compare
the results with both time division multiplexing and superposition modulation assuming a peak power limited AWGN channel. We show that significant gains can be achieved by properly designing the constellation set, specially in the presence of large SNIR imbalance between the user's link quality. We introduce two realistic case studies and present the results for each scenario.
