Design of Coded ALOHA With ZigZag Decoder

IEEE Access, 2019
In this study, we investigated the effects of combining a zigzag decoder (ZD) with a coded ALOHA using the successive interference cancellation (SIC) technique to retrieve packets from collisions.

Logic-Driven Semantic Communication for Resilient Multi-Agent Systems

IEEE Open Journal of the Communications Society
The advent of 6G networks is accelerating autonomy, intelligence, and interconnectedness in large-scale, decentralized multi-agent systems (MAS). While this evolution enables highly adaptive behavior, it also heightens vulnerability to stressors such as ...

A Cascade Deep Neural Network Approach for Compensation of RF Hardware Impairments in Wireless Transmitters

IEEE Open Journal of the Communications Society
Radio frequency (RF) hardware impairments can affect the transmit and receive signals in several ways, including deterioration of signal integrity, loss of power/spectral efficiency, and system performance degradation. While substantial efforts have been

Communication Efficient Federated Learning With Quantization-Aware Training Design

IEEE Transactions on Machine Learning in Communications and Networking
Model quantization is an effective method that can improve communication efficiency in federated learning (FL). The existing FL quantization protocols almost stay at the level of post-training quantization (PTQ), which comes at the cost of large ...
