Error Backprojection Algorithms for Non-Line-of-Sight Imaging [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2019 Recent advances in computer vision and inverse light transport theory have resulted in several non-line-of-sight imaging techniques. These techniques use photon time-of-flight information encoded in light after multiple, diffuse reflections to reconstruct a three-dimensional scene.

Indoor off-body wireless communication: static beamforming versus space-time coding [PDF]
, 2012 The performance of beamforming versus space-time coding using a body-worn textile antenna array is experimentally evaluated for an indoor environment, where a walking rescue worker transmits data in the 2.45 GHz ISM band, relying on a vertical textile ...

Multi-Channel Two-way Time of Flight Sensor Network Ranging [PDF]
, 2012 Two-way time of flight (ToF) ranging is one of the most interesting approaches for localization in wireless sensor networking since previous ToF ranging approaches using commercial off-the-shelf (COTS) devices have achieved good accuracy.

Non-Line-of-Sight Beacon Identification for Sensor Localization
International Journal of Distributed Sensor Networks, 2012 In recent years, sensors are often deployed to sense the target environment. Besides the sensed environmental information, sensor's position information itself is very important in most cases.

TOA localization for multipath and NLOS environment with virtual stations
EURASIP Journal on Wireless Communications and Networking, 2017 An effective geometrical method which can locate a source based on the time-of-arrival (TOA) measurements and the floor plan information is proposed in simple non-line-of-sight (NLOS) indoor environment where the multiple-bound scattering signal paths ...

Coverage and Rate Analysis for Unmanned Aerial Vehicle Base Stations with LoS/NLoS Propagation
, 2018 The use of unmanned aerial vehicle base stations (UAV-BSs) as airborne base stations has recently gained great attention. In this paper, we model a network of UAV-BSs as a Poisson point process (PPP) operating at a certain altitude above the ground users.
