Abstract

A location awareness system uses a wireless remote sensing technology to provide users with immediate addressing services. The application of radio frequency identification (RFID) technology to navigate a location is provided in this paper. The proposed UHF RFID location system, based on a known location of the reference tags by applying the cosine theorem to calculus more location information, can provide location-aware services. The cosine law can be realized by Coordinate Rotation Digital Computer (CORDIC) algorithm. In this paper, we present the implementation of a CORDIC (Coordinate Rotation Digital Computer ) processor based on the IEEE 754 Standard for Binary Floating-Point Arithmetic. The cosine law is implemented on DE2 circuit board and verified by logic analyzer.
