Outline of Research at the Start

Lattices are ordered arrangements of points in space that enable efficient information encoding. Unlike existing methods, they use the same real-valued algebra as communications channels. For future 6G wireless networks, this research aims to develop new lattice codes and apply them to improve reliability and multi-device communication efficiency. The goal is to extend device battery life, improve wireless data rates, and enhance connection stability for high-mobility wireless communications such as high speed vehicles.
