Measurement and Analysis of Channel Characteristics in Reflective Environments at 3.6 GHz and 14.6 GHz
Recently, high frequency bands (above 6 GHz) have attracted more attention for the next generation communication systems due to the limited frequency resources below 6 GHz. To reveal the influence of frequency on propagation channels, channel characterization results at 14.6 and 3.6 GHz bands based on measurements in an indoor scenario and in a reverberation chamber are presented. The measureme...
متن کاملINDOOR WIDEBAND RADIO PROPAGATION MEASUREMENT SYSTEM AT 1.3 GHz AND 4.0 GHz
This paper describes the development and operation of a dual-band time~domain radar system used to measure indoor multipath propagation characteristics in several office buildings and factories. The system operates at 1.3 GHz and 4.0 GHz, and uses 4 ns rms pulses to provide estimates of indoor radio channel impulse responses. The effects of ante.nna diversity, .frequency scaling, and topography...
متن کاملCapacity obtained from multiple-input multiple-output channel measurements in fixed wireless environments at 2.5 GHz
In this paper we present capacity, envelope correlation coefficient, and condition number statistics obtained from 2x2 Multiple-Input Multiple-Output (MIMO) fixed wireless radio channel measurements using dual-polarized antennas. To calculate the capacity, we assume that the transmitter has no knowledge about the channel. The experimental capacity results are compared to the informationtheoreti...
متن کاملJeq50224 1018..1025
Due to the difficulties in testing for specific pathogens, water samples are tested for the presence of nonpathogenic indicator organisms to determine whether a water supply has been contaminated by fecal material. An implicit assumption in this approach is that where pathogenic microorganisms are present fecal indicator organisms are present as well; yet surprisingly few studies have been cond...
متن کاملVela X at 31 Ghz
We present observations of the Vela X region at 31 GHz using the Cosmic Background Imager (CBI). We find a strong compact radio source (5A9 ; 4A1, FWHM) about the Vela pulsar, which we associate with the Vela pulsar wind nebula (PWN) recently discovered at lower radio frequencies. The CBI’s 40 resolution for a 450 field of view allows the PWN to be studied in the large-scale context of Vela X. ...
