Rate-Splitting Multiple Access With Finite-Alphabet Constellations: Precoder Optimization and Achievable Rate Performance

Rate Splitting Multiple Access (RSMA) precoder design with the practical finite-alphabet constellations instead of Gaussian inputs has been addressed in this paper. Considering a multiuser (MU) multiple-input single-output (MISO) broadcast channel (BC) system, we derive a generalized expression of t...
