Modeling and comparing different aircraft cabin wireless channel models

Stichworte:
RF, 3D-Model, ray-tracing, Aircraft Cabin

Beschreibung

Wireless communication is heavily dependent on the channel it operates on. Therefore, to simulate wireless transmissions, accurate wireless channel models are needed. The amount of channel models for aircraft cabins is quite limited and outdated because of the new materials used in aircrafts and new frequencies available for wireless transmission. Therefore, we want to develop a 3D structure of an two aisle aircraft cabin in Blender to simulate the propagation of electromagnetic waves. The goal of the thesis is to generate a wireless channel description of this model using ray-tracing and compare it to an existing single aisle model.

Voraussetzungen

6G MEC Optimization

Beschreibung

Aeronautical applications such as satellite communications and in aircraft systems have enhanced the range of applications for 5G, bringing new opportunities and potentials.

In the new 6G era these industries are envisioned to receive even more attention due to the high coverage possibilities that they provide. Applications such as unmanned aerival vehicles, flying taxis, moving base stations are just a few to name. In that regard, to support these wide range of applications, new 6G network urge for new and more efficient architectures.

In this thesis the student shall focus on the analysis of existing archiectures for 5G/6G for aeronautical applications and shall perform a comparison, definining potentials for the development of new architectures to reduce delay and increase the network performance. To this end, a comprehensive analysis is required to define the right metrics for comparison and identifying the potentials for improvement. An initial simulator based on the defined metrics is to be created to enable the comparison of similar algorithms in the future.

Voraussetzungen

    Good knowledge of simulation environments such as Matlab, Python.
    Good mathematical background.
    Knowledge about satellite communications is a plus.

Applying Machine Learning on a Beamforming Equation

Stichworte:
Beamforming, Optimization, Linearization

Beschreibung

Beamforming is a method for directional signal transmission and reception. Beamforming works by combining antenna elements, such that at particular angles constructive interference amplifies the signal, while for other angles destructive interference attenuates the wave. We formulated an optimization problem to maximize the sum rate of a network containing multiple access points by finding the optimum beam angles. This problem is formulated mathematically. The goal of this work is to digitize the formula and to solve the optimization problem by simplifying the formulation.

Voraussetzungen

- Python or Matlab programming experience
- Knowledge in optimization problems
- Knowledge in Sage or Gurobi (optional)
