In this paper, we develop an orthogonal frequency-division multiplexing (OFDM)-based over-the-air (OTA) aggregation solution for wireless federated learning (FL). In particular, the local gradients in massive Internet of things (IoT) devices are modula…
This paper presents a new coding scheme called semi-low-density parity-check convolutional code (semi-LDPC-CC), whose parity-check matrix consists of both sparse and dense sub-matrices, a feature distinguished from the conventional LDPC-CCs. We propose…
Due to its wide coverage, stable link, and low latency, cellular network has become one of the main access networks for Internet of things (IoT). However, the expenses of backhauls and node charging grow fast with the number of nodes. Towards this issu…
Ubiquitous information exchange is achieved among connected vehicles through the increasingly smart environment. The concept of conventional vehicular ad hoc network is gradually transformed into the Internet of vehicles (IoV). Meanwhile, more and more…
Beam scheduling is one of the most important issues regarding data relay satellite systems, which can improve the utilization efficiency of limited system resources by programming beam allocation for relay missions. The ever-increasing relay missions c…
