The Study on Constellation Mapping of Four-Dimensional in BICM-ID System

摘要：

In the BICM system, using multi-dimensional (MD) constellation mapping modulation can further increase the system bandwidth efficiency. This paper presents a constructing method of four-dimensional mapping of 16QAM and computer simulation results. The simulation results show that the four-dimensional mapping is superior to the two- dimensional mapping when the number of iterations is greater than a certain value.
