Indoor positioning and life detection using asynchronous multiple frequency shift keying radar system

Abstract

Indoor positioning and life detection using radio frequency has been widely researched, however, to achieve both indoor positioning and life detection has been a very challenging task until now. By careful design of the waveform and a novel detection algorithm, asynchronous multiple frequency shift keying(A-MFSK) is proposed to solve this task for the first time in this thesis, which can operate between a multiple frequency shift keying(MFSK) mode and a single tone continuous wave(CW) mode, providing a possibility of A-MFSK for this task. Detailed explanation about the detection algorithm is given. Simulations and measurements results of both modes demonstrate that A-MFSK has the capability of indoor positioning and life detection.
