多小区联合译码中的干扰对齐
Interference Alignment for Clustered Multicell Joint Decoding
摘要：
多细胞联合处理已被证明是非常有效的，在克服干扰有限的性质的蜂窝范例。然而，由于实际实现的原因，全局多小区联合解码是不可行的，因此必须考虑协作基站的集群。在这种情况下，集群间干扰必须得到缓解，以收获多小区联合处理的全部潜力。本文研究了四种簇间干扰情况，即a）全局多小区联合处理，b）干扰对齐，c）资源分多址和d）同信道干扰允许。每种情况下建模和分析使用每小区遍历和速率容量作为一个因素的优点。在这个过程中，一些定理推导出的信道协方差矩阵的渐近特征值分布的解析表示。分析是基于自由概率理论的原则，特别是在R和Stieltjes变换域的属性。
英文摘要：
Multicell joint processing has been proven to be very efficient in overcoming the interference-limited nature of the cellular paradigm. However, for reasons of practical implementation global multicell joint decoding is not feasible and thus clusters of cooperating Base Stations have to be considered. In this context, intercluster interference has to be mitigated in order to harvest the full potential of multicell joint processing. In this paper, four scenarios of intercluster interference are investigated, namely a) global multicell joint processing, b) interference alignment, c) resource division multiple access and d) cochannel interference allowance. Each scenario is modelled and analyzed using the per-cell ergodic sum-rate capacity as a figure of merit. In this process, a number of theorems are derived for analytically expressing the asymptotic eigenvalue distributions of the channel covariance matrices. The analysis is based on principles from Free Probability theory and especially properties in the R and Stieltjes transform domain.
