3-D Angular Spectrum Measurements in a Residential House at 5GHz
نویسندگان
چکیده
This paper presents an investigation of radio-wave propagation characteristics in the 5 GHz band in a residential two-story house. We investigated the 3-D angular spectra of incident waves when a transmitter and a receiver were set on the first floor and on the second floor, respectively. It was found that the strongest wave arrived at the receiving antenna from the direction of the transmitting antenna, penetrating through the ceiling of the first floor. Furthermore, we estimated the channel capacities of a 4-by-4 MIMO by using a 3-D angular spectrum. From this, a 1.6fold increase in capacity was achieved compared with that achieved in the horizontal plane by choosing a suitable elevation angle, including the direction of the transmitting antenna.

متن کاملA terminal Pleistocene child cremation and residential structure from eastern Beringia.
The dearth of human remains and residential sites has constrained inquiry into Beringian lifeways at the transition of the late Pleistocene-early Holocene. We report on human skeletal remains and a residential structure from central Alaska dated to ~11,500 calendar years ago. The remains are from a ~3-year-old child who was cremated in a pit within a semisubterranean house. The burial-cremation...

The vernacular body of the villages of Guilan, with its entanglement of paths, houses and agricultural fields, reveals the dispersed texture. The residential unit, side buildings and service spaces of the house are arranged erratically in the midst of relatively large areas. The enclosed fences are integrated with vegetation and trees and appear to be unconfirmed in a vague of being connected ...

Background :Soft tissue profile can be widely different in various populations. Furthermore, this profile can be also continues to change throughout life. However, there are few studies that quantitatively evaluate the soft tissue profile in Iranian population. In order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissu...
