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,介绍了分层空时码、空时格型码和空时分组码的编译码原理,比较了它们的优缺点,并给出了空时格型码的设计准则,最后分析了空时编码的研究动态。
Space-Time coding technique is the latest coding method for confronting channel fading and enhancing system＇s capacity. The coding principles for layered space-time code, space-time lattice code, and space-time block code are introduced, their advantages and disadvantages are compared, and the design criteria for space-time lattice code are given. Finally the current research status of space-time coding is analyzed.
