Fast Fading Characterization for Indoor to Indoor and Outdoor to Indoor Channels
2011 IEEE Vehicular Technology Conference (VTC Fall), 2011This work models the fast fading characteristics in indoor to indoor and outdoor to indoor channels at 3.8 GHz. Starting from real world measurements, the fast fading characteristics are extracted and properly modeled, taking into account the nodes movement conditions.

Multi-Polarized Channel Statistics for Outdoor-to-Indoor and Indoor-to-Indoor Channels
2010 IEEE 71st Vehicular Technology Conference, 2010Compared to classical spatial MIMO wireless systems, cross-polarized MIMO systems are an interesting way to reduce equipment size while reducing the inter-antenna correlation. Cross-Polar Discrimination (XPD) and Co-Polar Ratio (CPR) are two important parameters describing multi-polarized channels.

Indoor space subdivision for indoor navigation
Proceedings of the Sixth ACM SIGSPATIAL International Workshop on Indoor Spatial Awareness - ISA '14, 2014There are a number of great attempts to develop an indoor navigation that provide the most optimal path and guidance. Finding a way in large buildings can be a challenging task. In order to represent the real situation to a maximum extent, a representation of the whole room as one single indivisible object is not enough as such representation is very ...

The Replica Dataset: A Digital Replica of Indoor Spaces
arXiv.org, 2019We introduce Replica, a dataset of 18 highly photo-realistic 3D indoor scene reconstructions at room and building scale. Each scene consists of a dense mesh, high-resolution high-dynamic-range (HDR) textures, per-primitive semantic class and instance ...

Joint 2D-3D-Semantic Data for Indoor Scene Understanding
arXiv.org, 2017We present a dataset of large-scale indoor spaces that provides a variety of mutually registered modalities from 2D, 2.5D and 3D domains, with instance-level semantic and geometric annotations. The dataset covers over 6,000m2 and contains over 70,000 RGB

A Comparative Analysis of LiDAR SLAM-Based Indoor Navigation for Autonomous Vehicles
IEEE transactions on intelligent transportation systems (Print), 2021Simultaneous localization and mapping (SLAM) is a fundamental technique block in the indoor-navigation system for most autonomous vehicles and robots. SLAM aims at building a global consistent map of the environment while simultaneously determining the ...

Indoor sign Detection System for Indoor Assistance Navigation
2021 18th International Multi-Conference on Systems, Signals & Devices (SSD), 2021Indoor signage plays an important role in finding specific destinations and way-finding especially for blind and visually impaired people (VIP). In this paper, we developed a new indoor signage classifier using deep convolutional neural Network (DCNN).

2016 IEEE 32nd International Conference on Data Engineering (ICDE), 2016
A large part of modern life is lived indoors such as in homes, offices, shopping malls, universities, libraries and airports. However, almost all of the existing location-based services (LBS) have been designed only for outdoor space. This is mainly because the global positioning system (GPS) and other positioning technologies cannot accurately ...

Experientia, 1993
In industrialized countries most of the time is spent indoors. The basic ambient parameters for a thermally comfortable indoor climate are air temperature, air velocity, humidity and radiation pattern. Besides the thermal component, the concentrations of air pollutants in the indoor air are also of importance for wellbeing and health.

Indoor-indoor and indoor-outdoor propagation trial results at 2.6 GHz
2012 Loughborough Antennas & Propagation Conference (LAPC), 2012This paper presents delay spread, coherence bandwidth, and angle-of-arrival statistics derived from an extensive MIMO channel measurement campaign carried out at a central frequency of 2.6GHz. The measurement scenarios include indoor-indoor, indoor-outdoor and indoor-outdoor-indoor.
