In this article, a new radix-2 k signed-digit number (Radix-2 k sub signed-digit number) is defined and its properties for hardware realization are discussed. Until now, high speed calculation method with Radix-2 k signed-digit numbers is proposed, but this method used " Compares With 2 " to calculate carry. " Compares with 2 " is a very simple method, but(More)
We are currently developing a Regional Protection System in which children have terminals, and transponders installed at various locations receive packets sent from these terminals via a Specified Low-Power Radio System. The packets are then transmitted to a server so the positions of the children can be inferred from that information. With the ARIB STD-T67(More)
