基于NB-IoT硬件系统的低功耗算法研究

Front-end hardware system is an important part of LPWAN related technologies,the total power of the hardware system is an important index to evaluate its performances.DPM and DVS are two widely used algorithms in hardware systems.Based on the hardware low power scheme of NB-IoT and other and other underlying communication technologies,this paper proposes a process model in line with the existing hardware system,starting from the software algorithm of low power.A lower power solution based on the DPM algorithm is proposed,and its beneficial low power effest is verified.At the same time,based on the DVS algorithm,the factors that may affect the actual low power consumption effect are propsed for the practical problems existing in the hardware system,and the optimized algorithm is put forward to make the algorithm apllicable to more complex hardware systems.
