Abstract

Deep learning (DL) has appeared as a promising tool to re-design the physical layer by adding intelligence to the wireless networks requiring new features for future communications, such as large-scale topology, accurate processing, and high-speed requirements. These complex features present an opportunity for the success of DL-based frameworks because of the lack of mathematical models, the conventional methods fall short in practice. DL empirically fits the neural network model to the raw data and recent results have been extremely promising.
In this talk, we present the key issues of the wireless communication system design. Then, we show the potential of DL frameworks that aims to design all-in-one solutions. Later, we present challenges in designing DL-based physical layer communication, such as latency and space constraints, black-box nature, re-training issues, and data collection challenges. We also present recent applications of DL-based intelligent wireless networks, such as redesigning the conventional signal processing blocks for modulation, channel coding, and detection by replacing the communication system with an autoencoder for both the wireless and optical networks and performing mm-wave path-loss prediction for complex urban environments. We also focus on showing how to open the black-box of the DL-based designed wireless networks. Lastly, we present exciting new learning solutions for designing physical layer communications, such as deep reinforcement learning and model-based learning.
