摘要

提出了一种用于室内无线通信的多载波码分多址(MC-CDMA)系统。在频率非选择性衰落环境下，使用频率分集的MC系统不适用于典型的室内信道。这是因为子载波接收的包络具有相对于彼此的高度相关的衰落模式。为了获得独立的衰落模式，我们在MC-CDMA系统的子载波中引入了多个天线。对该系统的性能进行了分析，并与传统的MC-CDMA系统和带有分布式天线的CDMA系统进行了比较。

Multi-carrier CDMA system using multi-antenna for indoor wireless communication

This paper presents a multi-carrier code division multiple access (MC-CDMA) system for indoor wireless communication. MC systems using frequency diversity are not useful for typical indoor channels in a frequency nonselective fading environment. This is because the envelopes received by sub-carriers have highly correlated fading patterns with respect to each other. We introduce multiple antenna to the sub-carriers of the MC-CDMA system in order to obtain independent fading patterns. The performance of the proposed system is analyzed and compared with the conventional MC-CDMA system and CDMA system with distributed antenna.
