摘　　要：空时编码技术是抗信道衰落和提高系统容量的一种最新编码方法,这里简介了三种典型空时码:分层空时码、空时格型码和空时分组码,比较了它们的优缺点,并分析了下一代通信中空时编码的发展方向。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 capacity. This paper introduces briefly the three typical Space-Time codes, i.e. Layered Space-Time codes, Trellis Space-Time codes and Space-Time Block codes, and compates their advantages and disadvantages, an emphasis is put on the progress of the studies on this field.
