Indoor Radio Propagation Model Based on Dominant Path
When there are bigger obstacles in the indoor environment such as elevator, the radio waves basically can not penetrate it. The contribution of received signal strength by transmission and reflection will be greatly reduced, and most of the time, the radio waves will reach the user by bypass diffraction. Therefore, the traditional path loss model is no longer applicable, and the improved model ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولPhase modeling of indoor radio propagation channels
Two models for generating phase of individual multipath components in an indoor environment, partly developed in [1], have been studied in detail. In the deterministic phase increment model (model I), phase of each multipath component is updated deterministically using several independent random scatterers. In the random phase increment model (model II), phase of each multipath component is upd...
متن کاملGeometrically Based Channel Model for Indoor Radio Propagation with Directional Antennas
A geometrically based channel model is proposed to describe radio propagation in an indoor environment with directional antennas. In conventional geometric channel models (GCMs), distribution of scatterers does not take into account the antenna properties. A different approach is taken here for directional channel modeling. The locations of scattering objects are defined using nonCartesian coor...
متن کاملIndoor Radio Propagation Model Analysis Wireless Node Distance and Free Space Path Loss Measurements and Using Ultra-wideband (UWB) Technology
Ultra wide bandwidth (UWB) signals are commonly defined as signals that have a large relative bandwidth (bandwidth divided by the carrier frequency) or a large absolute bandwidth. Typical indoor environments contain multiple walls and obstacles consisting of different materials. The RF ultra wideband (UWB) system is a promising technology for indoor localisation owing to its high bandwidth that...
