Comparison of 28 GHz UMi Street Canyon Measurements With Map-Based Hybrid Channel Model
Autor: Gilbert Siy Ching, Hirokazu Yamakura, Yoto Emori, Yukiko Kishiki
Publikováno v: IEEE Access, Vol 12, Pp 159913-159918 (2024)
The map-based hybrid channel model is one of the candidates for managing stochastic components above millimeter waves. This model has been used in technical reports published by several well-known standardization organizations. This paper compares si

Autor: Mir Ghoraishi, M. Landmann, Gilbert Siy Ching, H. Sakamoto, Navarat Lertsirisopon, Itoji Sameda, Tetsuro Imai, Jun-ichi Takada
Publikováno v: IEEE Transactions on Antennas and Propagation. 57(no. 3):760-767
A wideband directional measurement campaign was managed inside an arched highway tunnel to analyze the radio propagation channel inside such tunnel for future cellular systems in terms of coverage, delay spread and dominant scatterers. Measurements w

Tunnel Propagation Channel Characterization for DSRC Applications
Autor: H. Sakamoto, Mir Ghoraishi, Itoji Sameda, Jun-ichi Takada, Gilbert Siy Ching, Tetsuro Imai, R. Soma, Navarat Lertsirisopon
Publikováno v: 2007 Asia Pacific Microwave Conference (APMC 2007). :479-482
The propagation channel characteristics of a transportation tunnel for DSRC applications is discussed. One problem in DSRC applications is that the received power in the adjacent (non-coverage) zone can be higher than the maximum allowed threshold. T

Analysis of DSRC Service Over-Reach inside an Arched Tunel
Autor: Hironori Sakamoto, Mir Ghoraishi, Navarat Lertsirisopon, Itoji Sameda, Jun-ichi Takada, Tetsuro Imai, Gilbert Siy Ching
Publikováno v: IEEE Journal on Selected Areas in Communications. 25(no. 8):1517-1525
In this paper, the prediction of received power in the out-of-zone of a dedicated short range communications (DSRC) system operating inside a typical arched highway tunnel is discussed. By conducting wideband directional channel sounding inside the t

Directional Channel Characteristics from Microcell Measurement and Simulation
Autor: Navarat Lertsirisopon, Gilbert Siy Ching, Mir Ghoraishi, Jun-ichi Takada, Ichiro Ida, Yasuyuki Oishi
Publikováno v: 2007 Asia-Pacific Microwave Conference.
In this paper, the channel predicted by using a ray- tracing simulator is presented and compared to microcellular measurement results performed inside a university campus. For data processing, the conventional beamforming is utilized to compare the d
