A cubic-receiver-based indoor optical wireless location system is proposed in this paper. The cubic receiver arranging five photodiodes (PDs) as a cubic structure is used as photodetector to measure the angles of arrival (AOAs) of the incident light from multiple light-emitting diodes. Due to the cubic structure. the AOA has a simple relationship with the differential received photocu... https://storeanimalwiz.shop/product-category/clothing/
