SCDMA系统中的多波束技术研究

Multi-beams Technique based on TD-SCDMA System

中文摘要英文摘要

智能天线技术对于抑制多用户干扰,降低发射功率是非常有效的。而现在的多径环境非常复杂,如何降低多径干扰也变成一个亟待解决的问题。本文提出一种基于TD-SCDMA系统的多波束方案。与一般所采用的单波束方法进行比较,所提出的方法在不需要降低接入用户量的基础上,系统性能较前者有一定提高。该方案在3GPP车载环境下进行仿真。

Smart antennas technique is an effective approach, which can cancel multiple access interference and reduce the transmit power. Due to the worse environment, it is necessary to decrease the influence of multi-path fading. In this paper, the multi-beams scheme based on TD-SCDMA system is investigated, which will not reduce the access users amount. Compared with the traditional single-beam scheme, the investigated one is more effective to improve the system performance. The vehicle environment which is recommended by the 3GPP is used in the simulation.
