Outage Probability of Full Duplex Relay in OLOS Underground Mine Environments

Abstract

Expanding the coverage of network with different techniques is necessity and demand of today’s life. As the population increases the demand for more solutions to give more capacity and to reach everyone on the whole world with network increases. This paper considers the design of dual-hop full-duplex (FD) Multiple-Input Multiple-Output (MIMO) Relay for workers in the underground mine tunnel area, with an obstructed line of sight OLOS conditions, where the relay is equipped with two antennas, while the source and destination are armed with a single antenna. This paper aims to investigate the outage probability performance when the communication channel is obstructed by a vehicle in a mine tunnel. In this case, the radio signal is obstructed, and no communication is possible, we proposed an investigative relay, installed around that vehicle, with scheme Zero-Forcing Beam-Forming (ZFBF) to avoid obstruction and enable communication again. The simulation results show that the proposed scheme can efficiently minimize the outage probability.
