Exact Line-of-Sight Probability for Channel Modeling in Typical Indoor Environments

The probability of line-of-sight (LOS) propagation is crucial for channel modeling and small-cell network evaluation. In this letter, by taking the layout of building structures into account, an analytical LOS probability model is proposed for typical indoor scenarios, which have rectangular rooms and corridors. The proposed model is validated through Monte Carlo simulations. Numerical results show that the proposed model estimates the network performance accurately and efficiently.
