Low-power LoRa wind sensor
Published 2020“…LoRa (Long Range) is a type of LPWAN protocol that stands out for being resilient to Doppler effect and its high channel capacity. This is attributed to its use of a variation of the Chirp Spread Spectrum (CSS) technology, of which LoRa PHY’s encoding and modulation process allows it to negate a high degree of interference and the time shift caused by the Doppler effect. …”

Human gait recognition by micro-doppler analysis of the signal
Published 2016“…Compared with physiological biometrics such as fingerprints or retina, it has behavioral characteristics which can be used to label or describe an individual according to their pattern of walk, theoretically supported by Micro-Doppler effect. In this report, an automatic gait recognition system is proposed and developed to achieve gender recognition and identity recognition. …”
