Abstract

Minkowski never met Shannon, yet the great minds do meet at lattice decoding—an innovative direction that connects lattice theory and digital communications. The model of a linear multi-input multi-output (MIMO) system apply to a range of important problems in digital communications, including code-division multiple access (CDMA)-based third-generation mobile communications, multi-antenna communications for broadband wireless services, and the linear dispersive intersymbol interference channels. In this talk I shall demonstrate the lattice description of a linear MIMO system and show the use of lattice algorithms to address the challenge of decoding complexity as well as a quantitative understanding of the performance of lattice decoding. I shall also outline the special problems that have to be addressed in the communications context and finally point out some open questions.
