Anode-free sodium–metal batteries (AFSMBs) with an Al current collector exhibit considerable energy density and cost-effectiveness, making them viable candidates for next-generation energy storage. Unfortunately, scarce Na nucleation sites on the Al current collector result in rapid dendrite growth, triggering rapid capacity decay …

Due to the correlation nature of underwater acoustic (UWA) channels, channels can be decomposed into the reduced-rank principal components and the corresponding channel subspace. A suitable rank in the subspace channel tracking is crucial for the performance. It relies on the correlation …

We consider the underwater acoustic channel which is time-variant and doubly-spread in this work. Since conventional channel estimation and decision feedback equalizer (DFE) can not work well for this type of channel, a path-specific underwater acoustic channel tracking is proposed. It is …

In this work, we focus on the model-mismatch problem for model-based subspace channel tracking in the correlated underwater acoustic channel. A model based on the underwater acoustic channel’s correlation can be used as the state-space model in the Kalman filter to improve …
