A Circuit Design for Ranging Measurement Using Chirp Spread Spectrum Waveform

摘要

This paper reports an RF circuit design for indoor localization using wireless chirp spread spectrum waveform. First we address the technical problems of existing hardware systems and then point out dominant factors of the ranging circuit. It will be shown that the performance of the existing system can be significantly enhanced by blocking the effects of clock noise. A set of experimental hardware circuits is developed and tested.
