摘要 分布式多天线结构的虚拟群小区系统成为未来无线系统的一种解决方案。该系统具有灵活的组织结构,在增加频谱效率、提高通信质量上具有巨大潜力,并且能为各种新技术的采用提供广阔的发展空间。该文采用Markov链逼近的方法分析多天线情况下虚拟群小区系统的系统性能,对于基于干扰的接入控制策略下的系统阻塞率,切换失败率等给出了数值结果。研究结果表明分布式多天线系统有效地提高了上行系统性能。 Distributed virtual group cell systems become a possible solution for future wireless communication systems, which has flexible structure and huge potential in terms of increasing spectrum efficiency and improving quality of communications. In this paper, a Markov model is adopted to analyze the porformance of multi-antenna based virtual group cell systems. Numerical results, such as blocking probability, handoff failure probability etc., arc given with interference-based admission control algorithm. The investigation shows that the uplink performance of this system can be improved greatly.
