摘要

提出了一种适用于CDMA分布式无线通信系统(DWCS)的天线动态选择算法。该算法采用“虚拟小区”(virtual cell, VC)中天线数量保持刚好合适的原则来动态调整“虚拟小区”(virtual cell)中天线的数量，而不是采用通常采用的每个“虚拟小区”中天线数量相同的天线静态选择(antenna static selection, ASS)方法。我们的研究表明，基于E/sub b//I/sub 0/的ADS在干扰有限的环境下是一种经济有效的解决方案，因为它可以实现与ASS几乎相似的中断容量，同时在欠载和过载系统中都比ASS显著降低天线成本。

A class of antenna dynamic selection algorithm based on E/sub b//I/sub 0/ in DWCS

In this paper a class of antenna dynamic selection (ADS) algorithm for CDMA distributed wireless communication system (DWCS) is proposed. In our algorithm, the number of antennas involved in a "virtual cell" (VC) is adjusted dynamically based on the rule of keeping just fit number of antennas in the VC instead of the common adopted antenna static selection (ASS) method that each VC contains same number of antennas. Our investigation shows that E/sub b//I/sub 0/-based ADS is a cost-effective solution in the interference-limited environment because it achieves almost similar outage capacity as ASS while reducing antenna costs significantly than that of ASS in both underloaded and overloaded systems.
