Abstract: In recent years, as discussions on the way how the information and communication technology (ICT) should be in Beyond 5G (B5G) and 6G are accelerating, the space laser communication is becoming more advanced and active in the field of space communications. The realization of the advanced communication network is expected to connect the terrestrial and non-terrestrial networks (NTNs) seamlessly. B5G/6G will require further global spatial expansion of the network than the current 5G, which direction is toward not only two-dimensional so far but also three-dimentional expansion for the mobile platforms called NTN in the future. In this talk, the trend and future vision of the space laser communication technology toward the B5G/6G will be introduced

His main current research interests include topological signal processing and learning, semantic and goal-oriented communications, 6G networks and distributed edge machine learning.

Abstract: The goal of this talk is to illustrate the potentials of a paradigm shift from the conventional Shannon-based approach to semantic and goal-oriented communications. The first part of the talk is devoted to the design of a goal-oriented communication network based on the information bottleneck (IB) method, as a principled way to identify and transmit only the relevant information with respect to the goal of communication. The IB principle is then exploited to derive a communication architecture that adapts the transmission data rate as a function of key performance indicators tuned to the application underlying the data communication. The rest of the talk is devoted to the use of probabilistic diffusion models as a way to design communication systems where the receiver, rather than tryng to recover all the transmitted bits used to encode a semantic message, regenerates a message that is semantically equivalent to the transmitted one. This approach provides many additional degrees of freedom that can be exploited to improve the effectiveness of wireless networks

Abstract: The evolution of mobile communications towards 6G will enable new applications and services that require a new radio interface able to meet new key performance indicators (KPIs). These mobile systems should be capable of operating in all kinds of environments, including some challenging ones that were not fully covered with 5G. What new requirements do we have for the waveform and the way the radio resources are organized? These have an enormous impact on the achievability of the KPIs and the ubiquitous provision of mobile services. This talk examines the properties, advantages, and disadvantages of some recently proposed waveforms and advocates that the key ingredient in this evolution is flexibility. Different ways to multiplex the pilots and data in an efficient way are explored as well, together with the option of not requiring any of them via non-coherent demodulation

Abstract: In the era of the Internet of Things (IoT), the deployment of resource-constrained embedded systems is proliferating, thus enabling the collection of heterogeneous data from objects, humans, animals and the environment. As the demand for intelligent decision-making at the edge grows, integrating machine learning and artificial intelligence into these networked embedded systems becomes imperative. However, the inherent limitations in terms of power, memory, and processing capabilities pose significant challenges. This talk explores the emerging paradigm of 'Tiny Machine Learning' (TinyML) as a transformative approach to enable intelligent processing on resource-constrained devices. We delve into the methodologies and techniques that make TinyML feasible for embedded systems and provide examples of complex AI tasks made 'tiny', emphasizing the need for efficient model architectures, lightweight algorithms, and favourable combinations of hardware and software.

Abstract: The recent proliferation of human activities in underwater environments, spanning environmental monitoring, underwater exploration, offshore oil field exploration/monitoring, disaster prevention, etc., has increased the need for reliable and secure underwater communications. In particular, as robotics play an ever-growing role in underwater missions and with recent advances in the design and development of autonomous underwater vehicles, there is a growing demand for broadband underwater links with significantly enhanced performance. In the context of the Internet of Underwater Things paradigm, underwater wireless optical communication emerges as a promising technology capable of providing very high data rates, low delay latencies, low energy consumption, and minimal environmental impact. This presentation provides an overview of the latest advancements in the UWOC links, with a specific emphasis on techniques aimed at enhancing link robustness, range, and data rate

Abstract: IEEE 802 has recently published two new standards for optical wireless communications. While IEEE Std 802.15.13-2023 is tailored for industrial, medical and backhaul applications, which require high reliability, low latency and zero jitter, IEEE Std 802.11bb-2023 is intended for the mass market aiming at low cost so that the reuse of existing silicon developed for 802.11, a.k.a. Wi-Fi has been defined. The talk will give a deeper insight into both standards, early product developments and open the discussion towards future work
