This study proposes a fusion algorithm based on forward linear prediction (FLP) and particle swarm optimization–back propagation (PSO-BP) to compensate for the temperature drift. Firstly, accelerometer signal is broken down into several intrinsic mode functions (IMFs) using variational modal decomposition (VMD); then, according FE algorithm, IMF separated mixed components, drift, pure noise. After that, noise denoised by FLP, PSO-BP employed create model adjustment. Finally, processed IMFs...
The technology of micro-energy harvesting offers a sustainable solution for addressing the worldwide energy crisis. efficient harvest wide-band and random vibration achieving its steady-state output remains significant challenge in pursuing green, low-carbon solutions. paper presents an automatic storage release harvester (ASSR) comprising counterweight unit, gearbox, generator. unit with low-frequency response can effectively sense weak vibration. is stored released by gear train switching...
Future communication systems must support high-speed mobile scenarios, while the mainstream Orthogonal Frequency Division Multiplexing (OFDM) technology faces severe inter-carrier interference in such environments. Therefore, adoption of Time–Frequency Space (OTFS) modulation 6G is an effective solution. The widely used single-pilot channel estimation OTFS susceptible to path loss and inaccurate fading coefficient estimation, leading reduced accuracy, signal distortion, degraded overall...
