Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, mobile communication terminals such as Smartphone are necessities of life, a number of terminals are present at high density in such train. Public wireless LAN service also increased with increasing the mobile communication terminal. It is expected that traffic becomes 10 times in 2020, insufficient capacity of the entrance circuit is concerned. Public wireless LAN service is provided in high-speed mobile such as the Shinkansen. It is the performance degradation cannot be controlled to fast channel fluctuation in the ordinary equalization, new measures are needed. We proposed that switching the receiving antenna in reverse order direction of travel of the train. It is the technology to fix the reception point at a fixed position, to slow down the channel change. The antenna switching technology has problems (1)setting of appropriate antenna element spacing, (2)timing and switching cycle of the antenna, (3)reduction of the influence of the circuit and switch,(4) responding to MIMO. In this draft, it is simulated the characteristics of the received signal for antenna switching technology as a basic study. Result of simulation, it obtained the reception characteristics as much as quiescent even when moving at high speed by the antenna switching technology has been found. However, as an error of antenna switching, the problem of discontinuity occurs in reception characteristics was found.
