Human motion and behavior analysis has become a new research field in pervasive computing. Aiming at the problems of high cost and low accuracy of current behavior identification methods. an efficient method MADR (multi-antenna joint decision efficient behavior recognition system) of CSI (channel state information) based on multi-antenna joint judgment is proposed. The method is divid... https://www.footballmediaservices.com/product-category/welding-filter-plate/
