A combined symbol constellation may be selected from a uniform symbol constellation that is supported by a de-mapper to provide additional power split options while reducing modifications to the de-mapper. In some examples, a signal may be constructed according to a combined symbol constellation selected from a larger uniform symbol constellation based on a desired power-ratio. The signal may include a base-layer, used to communicate a first set of data, and an enhancement-layer, used to communicate a second set of data, in accordance with the selected combined symbol constellation. The signal may be received and de-mapped according to the combined symbol constellation at a de-mapper that supports a uniform symbol constellation that is larger than the combined symbol constellation.
