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.
