Proposal of higher-order tensor independent component analysis for MIMO remote sensing systems

Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes higher-order tensor independent component analysis (HOT-ICA). HOT-ICA is a tensor ICA that makes effective use of the axial categories of a separating tensor. We deal with multiple-target signal separation in a multiple-input multiple-output (MIMO) radar system to detect respiration and heartbeat. In numerical physical experiments, our HOT-ICA system effectively measure and separate the bio-signals successfully even in an obstacle-affecting environment, which is usually a difficult task. The results demonstrate the significance of the HOT-ICA which keeps the tensor structure unchanged to fully utilizes the high-dimensionality of the separation tensor.
