Job Description

About this opportunity:

In modern mobile networks, the UE receiver must handle increasingly complex signal conditions especially when a base station transmits to multiple users simultaneously (MU-MIMO). Different receiver algorithms excel under different radio conditions, but knowing which one to use and when remains an open question in 3GPP standardization.

This thesis will investigate when advanced receivers (R-ML) outperform conventional ones (MMSE-IRC) for 5G/6G MIMO demodulation, and whether a simple AI classifier can learn to predict the better choice from observable radio parameters. You will use a physical layer simulator to generate data, analyze performance tradeoffs, and train a data-driven decision model.

What you will do:

• Study two MIMO receiver algorithms MMSE-IRC and R-ML to understand their strengths, limitations, and computational tradeoffs.
• Learn to run physical layer simulations using a Python-based simulator tool.
• Design and execute a structured simulation campaign comparing MMSE-IRC and R-ML across a range of conditions: SNR levels, channel models, and UE speeds. Then Analyze the results.
• Train a simple classifier that predicts the better receiver from easily observable radio parameters such as SNR, channel type, and Doppler spread.
• Visualize the findings through throughput curves, heatmaps, and decision boundaries that can be used in technical reports.
• Document your work.

The skills you bring:

• You are pursuing a B.Sc. in Engineering Mathematics or Computer Science.
• You have a solid foundation in Python and are comfortable with data analysis libraries (pandas, numpy, matplotlib).
• You have taken an introductory course in machine learning and understand basic concepts like classification, decision trees, and cross-validation.
• You have basic signal processing knowledge, understanding concepts like MIMO at a conceptual level.
• You are curious about wireless communications and interested in exploring how AI/ML can be applied to radio network problems.
• You can work both independently and as part of a pair, and communicate results clearly in written and spoken English.
