【摘要】 空时码具有频谱效率高、抗衰落能力强等突出优点。在介绍空时码的MIMO信息论基础上,系统地对三类空时码进行了分析比较。并对空时码在后3G这样的宽带移动通信系统中如何应用进行了探讨。更多还原

【Abstract】 Space time codes can achieve high spectral efficiency and robustly fight fading,so they have been studied extensively i n the region of wireless communicati on.In this paper,after introduc-ing MIMO information theory about sp ace time code,three kinds of space time code are compared and analyzed systematically.Some d iscussions about applying space tim e codes to beyond 3G wideband mobile communication are also made.更多还原
