Indoor millimeter-wave D2D communication modeling combining self-blockage and common blockage by Lei WANG, Xiao-ting YU, Ming-kai CHEN, Yi QIAN

“…The high transmission rate characteristic of millimeter wave (mmWave) technology can meet the requirements of large amount of data communications among intelligent devices for indoor scenario.While guaranteeing high throughput,reducing the interference simultaneously in a closed region is still a challenge.For indoor transmission,the human bodies are considered as main blockages besides common blockages.Thus,a new system model is presented,constructing the human body into a self-blockage model,while using multi-ball LOS link state model to describe the conventional blockage.The combination of the two will give a more comprehensive and accurate expression of indoor obstruction.The proposed model uses stochastic geometry to analyze system performance by giving a closed expression of coverage and rate.The simulation results show that the model is accurate to describe the distribution of blockages via the comparison between analysis and Monte Carlo simulations.…”
