GNURadio as a digital signal processing environment: Application to acoustic wireless sensor measurement and time & frequency analysis of periodic signals

摘要: The flexibility, reconfigurability and stability of software defined radio yield an attractive alternative to the analog strategy probing acoustic transducers acting as passive sensors probed through a wireless link or phase noise characterization oscillators. However, developing processing blocks is time consuming activity, yet metrology applications require dedicated understanding each step. We consider GNURadio means exploiting opensource optimum tradeoff between re-usability compatible with audit for assessing performance. This signal environment demonstrated on two practical examples, FMCW delay lines sensors, quartz tuning fork characterization. Both examples are considered introductory setups training teaching suitable research activities.
