Downlink SINR Statistics in OFDM-Based Optical Attocell Networks with a Poisson Point Process Network Model

Abstract

In this paper, the downlink signal-to-interferenceplus-noise ratio (SINR) statistics are analysed in a direct currentbiased optical orthogonal frequency division multiplexing (DCO-OFDM) based optical attocell network with a Poisson point process (PPP) cell deployment. An optical attocell system utilises existing lighting fixtures in an indoor environment to function as a small-cell cellular network. It uses each luminary as a base station (BS) to serve multiple nearby mobile users. Similar to a conventional radio frequency (RF) cellular system, the grid cell deployment is restricted by many practical issues in an optical attocell network. Therefore the performance of the system with PPP cell deployment is considered in this study in order to identify a lower bound for practical attocell networks with irregular cell deployment. An analytical framework is presented and compared with the computer simulations. Also the SINR statistics with different cell deployments are compared and discussed.Index Terms-cellular network, optical attocell network, Poisson point process, visible light communication.

Relay-Assisted Technology in Optical Wireless Communications: A Survey

“…Where, IOWC technology provides downlink connection through a relay, using RF technology to connect to the base station (BS). The hybrid RF/IOWC system is also considered in [11], [12], which is to improve user data rates and interrupt throughput. In [13], non-orthogonal multiple access performance of IOWC downlink is studied from two aspects of coverage probability and traversal rate.…”

Outage and BER performances of indoor relay‐assisted hybrid RF/VLC systems

“…Shlomi [11] studied the BER performance under the effect of clock time shift and jitter on the system using inverse pulse position modulation method. Furthermore, a hybrid RF/VLC system is considered in [12] to improve user data rates performance and outage throughput. In [13], the performance of the non-orthogonal multiple access in the VLC downlink is investigated in terms of the coverage probability and ergodic sum rate.…”
