Abstract

The paper explores the optimization of constellation geometry to improve throughput in wireless communication systems. It presents an approach where constellations can be unevenly distributed to enhance transmission efficiency. The optimization is performed on the base station side, and its effectiveness is validated through numerical experiments using LDPC coding, OFDM modulation, and MIMO technologies.

Keywords: Wireless, Constellation diagram, Geometric Shaping, Mutual Information
