This paper presents the measured radio propagation characteristics in outdoor environments for new mobile wireless system in the Jeju island at 781 MHz frequency. The propagation characteristics at 781MHz seem to be similar at 900MHz, but detailed characteristics can't be predicted without research for wireless communication system at the 781 MHz frequency. Also, there are few studies on process of...
Multiple-input multiple-output (MIMO) systems at the UHF bands is interest for wireless communication applications. When designing and evaluating such systems, knowledge of realistic propagation conditions is required. In this paper, the development of wideband MIMO channel sounder and a pilot measurement result is described for research on the multi antenna radio propagation characteristics considering...
This paper presents a statistical characterization of one Human Body Communication (HBC) channel model based on empirical data. The measurements which were conducted on a considerable amount of people guarantee the precision of the model. An adequate evaluation about the path loss, delay spread is convenience and appropriate to design the advanced wideband HBC system.
In this paper, the results of outdoor-to-indoor multiple-input multiple-output (MIMO) channel measurements at 780 MHz are presented. The motivation for these measurements was to provide actual measurement data needed to extend the International Mobile Telecommunications -Advanced (IMT-A) channel models to the frequencies around 400 - 900 MHz. There are publications reporting measurement results for...
The next generation mobile communication systems tend to wideband. We present the experimental results based on the polarimetric MIMO (Multiple Input Multiple Output) channel measurement campaign at 2.53 GHz with a bandwidth of 100 MHz, performed in Shanghai. Our special interest focuses on the propagation characteristics and channel parameters in terms of path loss, channel impulse response (CIR)...
