Spatial Dynamics of Indoor Radio Wideband Channels
The multipath components of superwideband (2–17.2 GHz) nonline-of-sight channel responses measured inside several buildings are stable along sections that are 27 cm long on average with a standard deviation of 16 cm. The stability regions of multipath components have an approximately log-normal histogram. An analysis of measured channels that explicitly includes finite spatial areas of visibili...
متن کاملSpatial and temporal characteristics of 60-GHz indoor channels
This article presents measurement results and models for 60-GHz channels. Multipath components were resolved in time by using a sliding correlator with 10-ns resolution and in space by sweeping a directional antenna with 7° half power beamwidth in the azimuthal direction. Power delay profiles (PDPs) and power angle profiles (PAPs) were measured in various indoor and short-range outdoor environm...
متن کاملMeasurement Analysis of Spatial and Temporal Correlation in Wideband Radio Channels with Adaptive Antenna Array
This paper investigates the spatial and temporal correlation by measurements of an 8-element adaptive antenna array. The channel measurement data is gathered at a 2.154 GHz range outdoor radio channel. The measurement analysis is divided into three different categories: Investigation of spatial correlation between antenna elements at the base station (BS), spatial correlation of different mobil...
متن کاملTemporal and spatial variation of the phytoplankton community in the Chahnime Reservoirs-Sistan
This study investigated seasonal changes in density and diversity of phytoplankton, chlorophyll a content, and some environmental characteristics in the Sistan region during 2014. Totally, we detected 28 genera that belonged to five groups of Chlorophyta (12 genera), Bacilloriophyta (7 genera), Cyanophyta (5 genera), Dinophyta (3 genera), and Euglenophyta (1 genus). We observed that Chlorophyta...
متن کاملWideband Propagation Measurements for Indoor Radio Channels at 62.4GHz
This paper reports 62.4GHz fixed wideband propagation measurements undertaken in six different LOS indoor environments (corridors and rooms) inside three buildings. Measurement analyses are presented in respect of static RMS delay spreads and received signal level. Uniformity of delay spread was observed for all the cases investigated. A correlation is observed with the static delay spread incr...
