Autor: Takada Jun-Ichi, Ida Ichirou, Oishi Yasuyuki, Sivasondhivat Kriangsak

Publikováno v: EURASIP Journal on Wireless Communications and Networking, Vol 2009, Iss 1, p 715403 (2009)

Abstract This paper focuses on the modeling of a double-directional power spectrum density (PSD) between the base station (BS) and mobile station (MS) based on the site-specific measurements in an urban macrocell in Tokyo. First, the authors investig

Mobile Station Spatio-Temporal Multipath Clustering of an Estimated Wideband MIMO Double-Directional Channel of a Small Urban 4.5 GHz Macrocell

Autor: Ida Ichirou, Oishi Yasuyuki, Materum Lawrence, Takada Jun-ichi

Publikováno v: EURASIP Journal on Wireless Communications and Networking, Vol 2009, Iss 1, p 804021 (2009)

Abstract Multipath clusters in a wireless channel could act as additional channels for spatial multiplexing MIMO systems. However, identifying them in order to come up with better cluster channel models has been a hurdle due to how they are defined.

Polarization Behavior of Discrete Multipath and Diffuse Scattering in Urban Environments at 4.5 GHz

Autor: Sivasondhivat Kriangsak, Takada Jun-Ichi, Ida Ichirou, Landmann Markus, Thomä Reiner

Publikováno v: EURASIP Journal on Wireless Communications and Networking, Vol 2007, Iss 1, p 057980 (2007)

The polarization behavior of the mobile MIMO radio channel is analyzed from polarimetric double-directional channel measurements, which were performed in a macrocell rural environment in Tokyo. The recorded data comprise non-line-of-sight, obstructed

Investigation of non-specular scattering by comparing directional channel characteristics from microcell measurement and simulation

Autor: CHING, Gilbert, Ching, Gilbert Siy, M., GHORAISHI, m, ghoraishi, Takada, Jun-ichi, Ida, Ichirou, OISHI, YASUYUKI

Publikováno v: IET Microwaves, Antennas & Propagation. 2:913-921

Channel characteristics from microcell measurement and simulation are compared. In microcell environment, the dominant propagation mechanisms are not only from reflections and diffractions from buildings but can also come from non-specular scattering

Autor: SIVASONDHIVAT, KRIANGSAK, sivasondhivat, kriangsak, Takada, Jun-ichi, Ida, Ichirou, OISHI, YASUYUKI

Publikováno v: IEICE Transactions on Communications. (no. 4):1132-1144

SUMMARY This paper experimentally studies and models the angulardelay power spectrum density at the mobile station based on the sitespecific measurement in a macrocell in urban area of Tokyo. The authors first show the azimuth power spectral density
