| 摘 要： | 在大多数散射环境下,天线分集是减小多径效应的一种实际、有效的技术,在分析Alamouti两发一收发射分集方案的基础上,介绍了一种基于导频符号辅助的发射天线选择分集方案.该方案通过引入反馈和导频符号辅助技术,在发射端对两个发射天线进行天线选择,给出的仿真结果表明,运用分集技术可大大改善无线通信系统的性能,该方案性能优于Alamouti两发一收发射分集方案,并且发送功率要低于Alamouti两发一收方案. |
| 关 键 词： | 无线通信 多径衰落 发射分集 天线选择 导频符号辅助 |

| Abstract: | In most scattering environments antenna diversity is a practical, effective and a widely applied technique for reducing the effect of multipath fading. After analyzing a simple transmit diversity scheme proposed by Alamouti a transmit antenna selection scheme based on pilot symbol assisted modulation is presented. The simulation has shown that the new scheme can improve the error performance and the radiated power is smaller than Alamouti scheme using two transmit antennas and one receive antenna. |
| Keywords: | Wireless communication Multipath fading Transmit diversity Antenna selection Pilot symbol assisted |
