摘　　要：空时编码是近年来发展很快的无线通信新技术,MIMO与空时编码结合的技术具有通信容量高,克服多径效应好等特点,在无线通信领域获得广泛应用。综述空时编码研究已取得的重要研究成果及其应用现状,介绍了集中式和分布式MIMO模型,分析比较了典型空时码的结构特点、主要特性和应用场合,指出其有待进一步研究解决的问题,分析了空时编码研究的发展方向。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.
