With the explosive growth of interconnected smart devices and sensors, the Internet has been entering the Internet of things (IoT) era and revolutionizing many aspects of our daily life. Meanwhile, crowdsourcing has been considered as a promising techn…
Nowadays, cloud computing has been identified as new opportunities for migrating to the expected agility, reuse, and adaptive capabilities that can support the ever changing IT trends and requirements. Unfortunately, the rapid evolution of those techno…
The performance of wireless communication systems is fundamentally constrained by the random and uncontrollable wireless channel. By leveraging the recent advances in digitally-controlled metasurface, intelligent reflecting surface (IRS) has emerged as…
The recently commercialized fifth-generation (5G) wireless networks have achieved many improvements, including air interface enhancement, spectrum expansion, and network intensification by several key technologies, such as massive multiple-input multip…
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…
