Abstract (in Japanese) (See Japanese page) 
(in English) We have been investigating Joint Transmission (JT), in which multi-access points (multi-APs) simultaneously transmit different data streams to a single station, and evaluating the transmission performance of JT in microwave‑band wireless LAN. In this paper, we investigate the impact of Carrier Frequency Offset (CFO) difference between two APs on the transmission performance of JT. Different from Multiple Input Multiple Output (MIMO) spatial multiplexing on a single AP, each stream experiences a different CFO because the two APs with different local oscillators transmit different streams. This paper discusses the effectiveness of CFO compensation method used in existing wireless LAN by link level simulation when the CFO differs across streams.
