Abstract (in Japanese) (See Japanese page) 
(in English) This paper investigates iterative carrier frequency offset (CFO) estimation with independent component analysis (ICA) in multiple-user multiple-input multiple-output (MU-MIMO) for Internet of things (IoT). In conventional CFO estimation in MU-MIMO, it is difficult to estimate the CFO directly from the spatially multiplexed received signal. Therefore, feeding back the estimated value of CFO to the terminals in advance using the pilot signal, we perform CFO compensation. However, by separating the spatially multiplexed signals using ICA, it is capable of estimating the CFO of each terminal individually without feedback of the estimated value of CFO in advance. In this paper, we propose a method using iterative estimation for CFO estimation and validate its effectiveness by computer simulations.
