High-speed and large-capacity communication has been realized by wireless LAN systems, but in the high-speed moving environments, BER performances degrade due to influence of Doppler frequency spread. In this study, the entrance link using the IEEE802.11ac standard for public wireless LAN services in high-speed trains is proposed for improving the capacity of the whole system by employing not only MIMO (Multiple Input Multiple Output) to increase the transmission rate, but also STBC (Space-Time Block Coding) to extend the distance. By applying unsymmetrical STBC for up and down-link, the communication distance between a base station and a train can be extended and it is confirmed by simulation including a passing pattern and stopping/starting pattern that the communication capacity can be increased.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.136 No.10 （2016） 特集：電気関係学会四国支部連合大会本誌掲載ページ: 1431-1436 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/136/10/136_1431/_article/-char/ja/
