瑞利衰落下多小区处理的中断概率
Outage Probability for Multi-Cell Processing under Rayleigh Fading
摘要：
多小区处理，也称为协调多点（CoMP），是一种非常有前途的分布式多天线技术，它使用相邻小区的天线。这有望成为下一代蜂窝网络标准（例如LTE-A）的一部分。密集城市环境中的小小区网络主要受到干扰的限制，而CoMP可以很好地利用这一事实来提高小区边缘用户的吞吐量。本文提供了一个分析推导的容量中断概率的CoMP经历快瑞利衰落。仅需要知道平均接收功率（慢变衰落），而不需要完美的信道状态信息（CSI）。成功接收的数据速率的优化，然后得出相对于合作站的数量和中断概率，示出了数值例子。
英文摘要：
Multi-cell processing, also called Coordinated Multiple Point (CoMP), is a very promising distributed multi-antennas technique that uses neighbour cell's antennas. This is expected to be part of next generation cellular networks standards such as LTE-A. Small cell networks in dense urban environment are mainly limited by interferences and CoMP can strongly take advantage of this fact to improve cell-edge users' throughput. This paper provides an analytical derivation of the capacity outage probability for CoMP experiencing fast Rayleigh fading. Only the average received power (slow varying fading) has to be known, and perfect Channel State Information (CSI) is not required. An optimisation of the successfully received data-rate is then derived with respect to the number of cooperating stations and the outage probability, illustrated by numerical examples.
