Propagation characteristics of wideband high-speed railway channel in viaduct scenario at 2.35 GHz
In order to obtain accurate characteristics of wireless channels in the viaduct area of China, a channel measurement was taken in a railway viaduct scenario of the Zhengzhou-Xi’an passenger dedicated line with a bandwidth of 50 MHz at 2.35 GHz. The single-slope log-distance model is used to analyze the path-loss (PL), and the distribution of shadow fading (SF) is obtained by statistical methods...
متن کاملSpatial Characteristics of 3D MIMO Wideband Channel in Indoor Hotspot Scenario at 3.5 GHz
Three dimension (3D) Multiple Input and Multiple Output (MIMO) with massive antenna elements, due to the advantage of using elevation domain than 2D MIMO, is regarded as a promising technique for the fifth generation (5G) mobile communication systems. This makes the channel characteristics of elevation domain as a basic requirement for the 5G channel model. In this paper, we conducted a 3D MIMO...
متن کاملRicean K-Factor Measurements and Analysis for Wideband High-Speed Railway Channels at 2.35 GHz
This paper presents the analysis of Ricean K-factor for wideband high-speed railway channels at 2.35 GHz, based on radio channel measurements under viaduct and U-shape cutting scenarios. We characterize the K-factor from the perspective of narrowband, wideband and delay, according to the measured channel responses. The time-frequency varying narrowband K-factors in two scenarios are analyzed an...
متن کاملPropagation characteristics for wideband outdoor mobile communications at 5.3 GHz
In this paper, empirical channel models and parameters are derived from the wideband measured data at 5.3 GHz in outdoor mobile communications. The path loss exponents and intercepts are obtained by using the least square method. The mean excess delay and mean root-mean-square (rms) delay spread are within 29–102 ns and 22–88 ns, respectively. The correlation distances and bandwidths are within...
متن کاملIndoor Office Wideband MIMO Channel Characteristics at 3.7 GHz
In this paper, we present propagation characteristics of the wideband MIMO channel based on indoor measurement. Statistical characterization of the wideband MIMO channel is crucial for the design of wireless mobile broadband communication systems, especially upcoming IMT-Advanced systems. We performed measurement campaign for the indoor office scenario using the Band Exploration and Channel Sou...
