Abstract (in Japanese) (See Japanese page) 
(in English) The IEEE802 Committee has standardized 802.11ac to realize high-speed communication over 1Gbps. In order to realize high-speed and large-capacity capabilities, it has been developed by employing advanced MIMO（Multiple Input Multiple Output）technologies. But this method increases training signals to estimate the propagation matrix of multi-antenna system. In this study, corresponding to the frame structure of 802.11ac, the throughput improvement has been studied by shortening the training signals（VHT-LTF : Very High Throughput – Long Training Field）.
