摘要
发送分集技术是第三代移动通信系统(3G)中的一种关键技术。主要分析了两种基于空时编码的发送分集:STTC和STTD。从成对错误概率角度和误码率等方面讨论了两种发送分集的性能。最后,进行了计算机仿真,并给出结论。
Transmiting Diversity is key technology in 3G (the third generation mobile communication). This paper is mainly analyzed two kinds of Transmiting Diversity based on space-time coding: STTC and STTD. It is discussed the performance from error probability and error rate. In the end, the computer simulations and the conclusion are given.
