Summary: In beyond 5G radio networks, distributed array antennas can be used to serve different users in a coherent manner.  To make everyone happy, we have to steer beams and allocate certain bandwidth to specific users to satisfy the data rate requirements. Different users could experience varying frequency-selective channel conditions. There exists challenges such as subcarrier allocation along with beam focusing and power allocation.

Problem definition: This thesis focuses on addressing these challenges by formulating and solving optimization problems, providing practical solutions for applications like 5G, IoT, or  vehicular communications.

Description:

Method: The project will involve following steps: 
1. System modelling: model the system mathematically.
2. Problem formulation: define optimization problems, performance metric, objective functions and constraints.
3. Solve the formulated problem: deterministic methods (linear programming, semi-definite relaxation…) or stochastic methods (genetic algorithm, particle swarm…)
4. Performance analysis: Evaluate the obtained solution, state strengths and limitations of the proposed approach.

Requirements:

You are familiar with MATLAB. You have a background in Electrical Engineering or Computer Science, have knowledge in wireless communication, optimization, or willing to learn related skills.
