摘要
在第3代移动通信系统中,空时编码(space-time coding)技术是抗信道衰落和提高系统容量的一种最新编码方法。文章综述空时编码技术的产生、基本原理和应用简况,并分别介绍三种空时编码方法的特点。
Space-time coding technique is a new coding technique which can combat with channel attenuation, obtain diversity gain against fading and enhance the data rate and / or capacity. This paper summarizes the basic principles of space-time coding and the features of 3 different space-time coding are introduced briefly. At last we sum up the round application status of space-time coding.
