Sinh Cong Lam, Kumbesan Sandrasegaran

摘要:

空间泊松点过程(PPP)网络的基站(BS)按照泊松分布,目前被用作分析蜂窝网络性能的精确模型。目前对瑞利衰落信道下PPP网络性能的研究大多假设基站具有固定的发射功率,每个小区只有一个资源块(RB)或一个用户。在本文中,瑞利对数正态衰落信道中,它被认为是假设每个小区被分配$N$资源块(RB)服务于M个用户。此外,假设典型用户的服务BS和干扰BS以不同的功率电平进行发送。利用高斯-勒让德近似,推导了低信噪比和高信噪比下网络覆盖概率的封闭表达式。分析结果表明,当SNR<10 dB,λ<1时,典型用户的性能与基站的发射功率和密度成正比;当SNR>10 dB,λ>1时,典型用户的性能达到上界。考虑了蒙特卡罗模拟的方差,验证了模拟结果的稳定性和准确性。

英文摘要:

Spatial Poisson Point Process (PPP) network, whose Base Stations (BS)s are distributed according to a Poisson distribution, is currently used as a accurate model to analyse the performance of a cellular network. Most current work on evaluation of PPP network in Rayleigh fading channels are usually assumed that the BSs have fixed transmission power levels and there is only a Resource Block (RB) or a user in each cell. In this paper, the Rayleigh-Lognormal fading channels are considered, and it is assumed that each cell is allocated $N$ Resource Blocks (RB) to serve M users. Furthermore, the serving and interfering BS of a typical user are assumed to transmit at different power levels. The closed-form expression for the network coverage probability for both low and high SNR is derived by using Gauss-Legendre approximation. The analytical results indicates that the performance of the typical user is proportional to the transmission power and density of BSs when SNR<10 dB and λ<1, and reaches the upper bound when SNR>10 dB or λ>1. The variance of Monte Carlo simulation is considered to verify the stability and accuracy of simulation results.
