As a new technology of wireless communications, Space-time coding is developing rapidly in recent years. Particularly, Space-time Coding has been applied in combination of MIMO to provide high capacity and good multi-path mitigation characteristics, which presents a good prospect in wireless communications. In this paper, research results and their application status of Space-Time Coding are first described. Secondly, centralized and distributed MIMO models are introduced. Then,analysis and comparison of the typical structural characteristics of Space-Time Code, its main features and applications are presented. Finally it identifies some key issues to be studied further and future development direction.
