无线网络中SINR Meta分布的一种主干扰加平均场近似

A Dominant Interferer plus Mean Field-based Approximation for SINR Meta Distribution in Wireless Networks

Yujie Qin, Mustafa A. Kishk, Mohamed-Slim Alouini

摘要:

本文提出了一种新的方法来计算信号与干扰加噪声比(SINR)的下行链路传输在瑞利衰落的无线网络的Meta分布。新的方法依赖于精确和平均场分析的干扰(占主导地位的基于近似)的近似组合,以降低分析的复杂性和提高易处理性。特别地,所提出的近似省略了计算SINR的一阶矩或二阶矩的需要,所述SINR的一阶矩或二阶矩用于文献中通常采用的β近似,但是需要计算联合距离分布。我们首先推导了基于具有标准路径损耗和瑞利衰落的泊松点过程(PPP)网络的近似,然后在另外四种广泛使用的点过程:泊松双极网络、Matérn簇过程(MCP)、$K$层PPP和泊松线Cox过程(PLCP)中说明了其准确性和可操作性.具体地说,我们首次获得了PLCP网络的SINR Meta分布。尽管所提出的近似看起来很简单,但与流行的beta近似以及蒙特卡洛模拟相比,它显示出良好的匹配,这为在更先进的网络架构中采用这种近似打开了大门。

英文摘要:

This paper proposes a novel approach for computing the meta distribution of the signal-to-interference-plus-noise ratio (SINR) for the downlink transmission in a wireless network with Rayleigh fading. The novel approach relies on an approximation mix of exact and mean-field analysis of interference (dominant interferer-based approximation) to reduce the complexity of analysis and enhance tractability. In particular, the proposed approximation omits the need to compute the first or the second moment of the SINR that is used in the beta approximation typically adopted in the literature but requires of computing the joint distance distributions. We first derive the proposed approximation based on a Poisson point process (PPP) network with a standard path-loss and Rayleigh fading and then illustrate its accuracy and operability in another four widely used point processes: Poisson bipolar network, Matérn cluster process (MCP), $K$-tier PPP and Poisson line Cox process (PLCP). Specifically, we obtain the SINR meta distribution for PLCP networks for the first time. Even though the proposed approximation looks simple but it shows good matching in comparison to the popular beta approximation as well as the Monte-Carlo simulations, which opens the door to adopting this approximation in more advanced network architectures.
