| 摘 要： | 结合空间分集和极化分集，对MIMO—OFDM系统中的容量进行研究。在IEEE 802．16d室内多径环境下，对使用2根发射天线和2根接收天线的MIMO—OFDM系统进行了深入研究。在发射端和接收端，空间分集和极化分集技术同时应用在MIMO—OFDM系统中。为了比较，对仅使用空间分集的通信系统容量也进行了讨论。 |
| 关 键 词： | 容量分析 极化分集 空间分集 MIMO—OFDM |

| Abstract: | Capacity of the MIMO - OFDM systems using both space diversity and polarization diversity was analyzed. Based on a multi -path channel model defined by IEEE 802.16d indoor channel standard,an MIMO - OFDM system with two transmitter antennas and two receiver antennas was investigated. The space diversity and the polarization diversity were simultaneously applied both in the transmitter and the receiver. The capacity of a system exclusively used in spatial diversity was also examined for better comparison. |
| Keywords: | capacity analysis polarization diversity space diversity MIMO - OFDM |
