摘要

Binary physical-layer Raptor (PLR) codes are known to be capable of approaching the channel capacity over the binary-input additive white Gaussian noise (BIAWGN) channel efficiently. It is desired to apply PLR codes to high order modulations to achieve good spectral efficiency. Herein we study the designs of using conventional PLR codes and protograph-based PLR codes by taking standard Gray-mapped 16QAM into consideration. Simulation results are presented to show the advantages of various designs.
