摘要

简要描述了第三代(3G) CDMA蜂窝标准的开环发射分集(TD)方法。这些解决方案基于基站的正交信号传输，以减少同小区干扰。研究了这种正交信号传输方式对系统性能的提高，并与传统方案进行了比较。本文还给出了基于Shannon容量极限的性能界限，以比较和对比TD方法之间的几个基本差异。

Open-loop transmit diversity for CDMA forward link

Open-loop transmit diversity (TD) methods for the third generation (3G) CDMA cellular standards are briefly described. These solutions are based on orthogonal signal transmission from the base station to reduce same-cell interference. The performance enhancement due to this orthogonal signal transmission is studied and it is compared with traditional schemes. Performance bounds based on the Shannon capacity limit are also given to compare and contrast several fundamental differences among the TD methods.
