Abstract
Systems, methods, apparatuses, and computer program products for probabilistic amplitude shaping (PAS) are provided. One method may include selecting a distribution parameter for one constellation in a communications system depending on one or more flat fading channels, transforming a uniform distribution of the constellation into a shaped distribution using the selected distribution parameter to produce modulated data, and passing the modulated data through a fading channel.
