Multihop relay techniques for communication range extension in near-field magnetic induction communication systems [PDF]
, 2013 In this paper, multihop relaying in RF-based com munications and near field magnetic induction communication (NFMIC) is discussed. Three multihop relay strategies for NFMIC are proposed: Non Line of Sight Magnetic Induction Relay (NLoS-MI Relay), Non ...

Average power prediction in microcells [PDF]
, 1994 A propagation model to estimate the average received power in an urban microcell environment has been developed. This model can be used both in line of sight (LOS) and non line of sight (NLOS) conditions in any regular or irregular microcell structure ...

Non-line-of-sight reconstruction via structure sparsity regularization
Optics Letters, 2023 Non-line-of-sight (NLOS) imaging allows for the imaging of obje¬¬cts around a corner, which enables potential applications in various fields such as autonomous driving, robotic vision, medical imaging, security monitoring, etc. However, the quality of reconstruction is challenged by low signal-noise-ratio (SNR) measurements. In this study, we present a

Non-line-of-sight Reconstruction Using Efficient Transient Rendering [PDF]
ACM Transactions on Graphics, 2020 Being able to see beyond the direct line of sight is an intriguing prospect and could benefit a wide variety of important applications. Recent work has demonstrated that time-resolved measurements of indirect diffuse light contain valuable information for reconstructing shape and reflectance properties of objects located around a corner.
