Practical Wi-Fi-based Motion Recognition Under Variable Traffic Patterns

Researchers propose a transformer-based neural network (SRV-NN) that enables Wi-Fi sensing systems to recognize human motions and gestures despite variable transmission traffic patterns and sampling rates. The approach uses dynamic sampling rate augmentation to improve generalization, demonstrating enhanced accuracy and stability across inconsistent data conditions compared to traditional fixed-rate methods.

Resource-Element Energy Difference for Noncoherent Over-the-Air Federated Learning

Researchers propose REED (Resource-Element Energy Difference), a noncoherent aggregation method for over-the-air federated learning that eliminates the need for instantaneous channel state information. The technique uses energy differences across orthogonal resource elements to aggregate signed updates, achieving convergence rates comparable to conventional methods while reducing practical implementation complexity in wireless systems.
