In this paper, we study the mechanism design of opportunistic spectrum access (OSA) in cache-enabled cognitive radio (CR) networks based on interference cancellation (IC). Particularly, we propose an IC-based OSA protocol under which a secondary transmit device (STx) can access the spectrum when it is detected in eithe...

Integrating over-the-air computations into the model aggregation process of federated learning (FL) offers a promising solution to mitigate the communication bottleneck in FL model training. In this approach, all the clients modulate their intermediate parameters, such as gradients, onto the same set of orthogonal wave...

Federated learning (FL) applications normally employ large deep learning (DL) models, resulting in excessive communication overhead in the deployment of FL over resource-constraint mobile edge networks. To achieve better scalability for DL-based FL, we capitalize on both the asymmetric nature of mobile networks and the...
