Description In the latest years a novel paradigm in communications has arisen: a massive amount of devices need to communicate via a wireless medium carrying small data units in an efficient manner. Departing from classical medium access protocols, novel Internet of Things (IoT) solutions aim at providing cost-effective and energy- efficient schemes. Both proprietary solutions like SigFox and LoRaWAN as well as standards like NB-IoT have been already successfully deployed. At our department, alternative solutions based on advanced random access schemes employing both strong error-correcting codes and multi-user detection techniques have been designed, analyzed and tested via prototypes. The thesis/internship aim is to design a detailed PHY and MAC simulator able to provide the performance of one (or more) of SigFox, LoRaWAN with its latest embodiement, LoRa-e and NB-IoT schemes. Detailed characterization of the packet payload as well as of the channel model is required. At the receiver side, starting with a simple idealized scenario (ideal detection, channel estimation, emulation of the channel decoding procedure via e.g. Normal Approximation), we will move towards a more sophisticated receiver able to cope with detection, time, frequency and phase estimation as well as channel estimation. Finally, channel decoding will also be performed. |

Description The internet of Things (IoT) is attracting an increasing attention from both industry and academia, and will be a core component of the next generation 6G systems. In an IoT network, a potentially massive number of low-cost, low-complexity devices generate traffic to be reported to a common receiver monitoring the situation. Relevant examples include asset tracking, industrial and environmental monitoring, smart cities, as well as cyber-physical systems. In such a scenario, the possibility to let a large amount of concurrent transmissions coexist is key to improve the spectral efficiency and reliability of the next generation communication systems. Small data units sporadically transmitted by a vast population of terminals with low- to very-low duty cycle, poses unprecedented challenges to the multiple access design. Coordinating the transmission entails an overhead that may grow unbearably with the total population size and not with the number of active users, which might be order of magnitude lower. Further, such terminals might be battery powered and hence low energy consumption is key. The aim of the thesis is to evaluate how machine learning can aid and possibly enhance the detection of small data packets transmitted asynchronously and uncoordinatedly. In modern random-access solutions, several overlapping packets may anyhow be decoded, thanks to powerful forward error correction, interference cancellation and other advanced signal processing techniques. In these scenarios, packet detectors are required to operate in a very harsh environment with unfavorable signal-to-noise and interference ratio. Additionally, detection algorithms that are theoretically optimal are difficult (if not impossible) to devise, due to the exponential number of possible interference cases that may arise in an uncoordinated and asynchronous access policy. Machine-learning algorithms appear to be very suited to such cases and in the thesis we would like to explore what relevant supervised learning algorithms may be beneficial, taking into consideration relevant trade-offs, in terms of e.g. complexity, detection performance, etc. |

In an IoT network, a potentially massive number of low-cost, low-complexity devices generate traffic to be reported to a common receiver monitoring the situation. Relevant examples include asset tracking, industrial and environmental monitoring as well as smart cities. In this context, the possibility to collect IoT messages via constellations of small satellites in low-Earth orbit is a key enabler to provide global connectivity, and has recently been introduced by 3GPP as part of the 5G standard. The reception of data at satellites that fly at high speed poses however also a number of technical challenges, such as signal distortions due to Doppler shift. The design of advanced waveforms at the physical and medium access control layer to enable efficient IoT communications via non-terrestrial networks will thus play a key role for the development of upcoming communications systems. The thesis will focus on the investigation, also by means of network simulations, of the narrow-band IoT (NB- IoT) waveform currently supported by the 5G standard. Its performance over satellite links will be studied, in comparison with other recently proposed solutions for massive IoT access. The student will have the chance to learn about IoT systems, satellite-based communications, and become familiar with protocols that are a core part of 5G and next generation wireless standards. |

Internship job offer for bachelor and master students in the field of photonics, electronics, electrical and telecommunication engineering.
Lumileds R&D is searching for graduate and undergraduate students willing to contribute to the solid state lighting industry. The student(s) will work in a high-tech industry facility alongside a professional research team of electrical engineers and physicists. The specific research project focuses on metasurfaces for Solid State Lighting applications, with a particular emphasis on artificial and virtual reality. As these technologies continue to advance, the demand for higher resolutions, larger contrast, higher efficiencies, and compactness is ever-growing. These challenges require solutions that involve cutting-edge technologies in various disciplines such as optical engineering, photonics, and solid-state lighting. Some of the main challenges to be accomplished by the next generation of artificial and virtual reality devices require the development of ultra-small micro LEDs. Despite the size specifications of these micro LEDs, it is necessary for them to maintain high efficiency, brightness, and also provide specific radiation patterns. In this context, metasurfaces appear as one interesting element to achieve some of the goals, thanks to their ability to control light propagation and emission in compact spaces.
The student(s) ' responsibilities will involve developing computational methods to analyze metasurfaces' response and design optimal structures.
Responsibilities: - Conduct literature research on the use of metasurfaces to control various desired properties of light. - Develop and test numerical models to solve light propagation in nanostructures. |

Context The Nokia Aalborg department is part of the Nokia Standards organization, which supports development of 3GPP Radio Access specifications.
Project Network energy savings are necessary to decreases the CO2 footprint from the cellular industry. With Non-Terrestrial Networks (NTN) through for instance LEO satellites providing coverage everywhere they can serve as coverage layer for all traffic, such that terrestrial cells can be switched off when traffic loads are low. To enable this without degradation of service it requires mechanisms to quickly switch on the relevant terrestrial cells when the load in a certain area increases and good seamless mobility solutions between TN and NTN. Description The project has the following objectives:
