  1. 16. Improvement of the robustness and performance of time of arrival algorithms

    University essay from Uppsala universitet/Signaler och system

    Author : Kristian Huotila; [2021]
    Keywords : ;

    Abstract : 5G offers several new improvements compared to its predecessors, such as higher speeds, lower latency and larger capacity. In order to ensure this, time of arrival algorithms are used in the Radio Access Networks for several purposes. Some of them are 3D positioning of User Equipment and synchronization. READ MORE

  3. 17. Semantic Segmentation of Building Materials in Real World Images Using 3D Information

    University essay from Linköpings universitet/Datorseende

    Author : Jonas Rydgård; Marcus Bejgrowicz; [2021]
    Keywords : Machine learning; deep learning; semantic segmentation; convolutional neural networks; building materials; material recognition;

    Abstract : The increasing popularity of drones has made it convenient to capture a large number of images of a property, which can then be used to build a 3D model. The conditions of buildings can be analyzed to plan renovations. This creates an interest for automatically identifying building materials, a task well suited for machine learning. READ MORE

  4. 18. Physical Layer Security With Active Jamming Using NOMA.

    University essay from Blekinge Tekniska Högskola

    Author : Mounika Polisetti; [2021]
    Keywords : Physical Layer security; secrecy capacity; eavesdropper; spectral efficiency; secure NOMA transmission;

    Abstract : This paper is persuaded to understand the physical layer security in wireless commu-nications utilizing NOMA (Non Orthogonal Multiple Access) concepts in the presence of an eavesdropper. Physical layer security maintains the confidentiality and secrecyof the system against eavesdroppers. READ MORE

  5. 19. Performance Analysis of a Non-Orthogonal Multiple Access in MIMO Setup

    University essay from Blekinge Tekniska Högskola

    Author : Sankeerth Kumar Poojala; Venkata Sai Teja Vedavalli; [2021]
    Keywords : Non Orthogonal Multiple Access; NOMA; Multiple Input Multiple Output; MIMO; 5G;

    Abstract : With the advancement of wireless communication systems, the demand for higher data rates is increasing exponentially. Non Orthogonal Multiple Access (NOMA) is expected to play an important role in 5G new radio networks. In contrast to conventional multiple access schemes, NOMA allows different users to efficiently share the same resources (i.e. READ MORE

  6. 20. Lean Beam Management for New Radio

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nawanit Kumar; [2020]
    Keywords : 5G; NR; MIMO; Beam management; CSI-RS; Technology and Engineering;

    Abstract : The use of millimetre-wave frequencies in Fifth generation New Radio has lead to high path loss due to radio propagation environment. Simultaneously, high data rates is a must for current products due to high market demand. This requirement accounts for efficient tracking of the best beam for the user equipment to stay connected to it. READ MORE
