- Abstract
- This paper proposes a new 4-dimensional constellation-rotation (CR) method that uses two consecutive CR operations for the constellation of QAM signals. The computer simulation results show that the proposed method performs better than a conventional 2-dimensional CR method as both a channel code rate and an erasure ratio increase. ©2011 IEEE.
