Mobility Classification of LoRaWAN Nodes Using Machine Learning at Network Level

open access: yesSensors, 2023
LoRaWAN networks rely heavily on the adaptive data rate algorithm to achieve good link reliability and to support the required density of end devices. However, to be effective the adaptive data rate algorithm needs to be tuned according to the level of ...

Adaptive Demodulation in Differentially Coherent Phase Systems: Design and Performance Analysis

open access: yes, 2010
Adaptive Demodulation (ADM) is a newly proposed rate-adaptive system which operates without requiring Channel State Information (CSI) at the transmitter (unlike adaptive modulation) by using adaptive decision region boundaries at the receiver and ...
