Method and apparatus of constellation design for step-shaped hierarchical modulation

摘要

The present invention discloses a method and apparatus for designing a constellation based on stepped hierarchical modulation. According to the present invention, a processor and a memory connected to the processor are included, wherein the memory generates an initial constellation including M (M is a natural number) signal points based on a stepped θ-QAM, and protects data Set a constellation parameter for adjusting the degree, apply the constellation parameter to the initial constellation to move the signal points located in the m-th quadrant by a preset distance in a preset direction, and An apparatus for designing a stair-step hierarchical modulation-based constellation that stores program instructions executed by the processor to map the encoded information bits is provided.
