Master Thesis: Characterizing hardware imperfection of power amplifiers
Be an Early Applicant
Conduct a master’s thesis analyzing hardware imperfections in power amplifiers using realistic testbed data. Review conventional and neural-network modeling techniques, develop and implement suitable models in an existing simulation framework, compare model performance and complexity, and perform analytical studies to provide insight into hardware behavior. Relevant backgrounds include electrical engineering, computer science, machine learning, signal processing, deep learning, and radio-frequency components.

About this opportunity:
In the field of electronics, hardware components exhibit a wide range of behaviors that can vary significantly under different conditions impacting their performance or operation accuracy and efficiency. These deviations are commonly known as hardware imperfections. Modeling the behavior of these devices is often a complex and challenging task. Our hardware engineering unit at Ericsson holds a keen interest in modeling and predicting the behavior of such devices.
At the forefront of this endeavor, state-of-the-art techniques such as neural networks have gained recognition for their ability to accurately capture and predict the diverse behaviors exhibited by such devices. By leveraging the power of neural networks, engineers and researchers are able to develop models that effectively characterize often unpredictable nature of these devices.
Accurate and reliable models can bring insight to the ways that we could mitigate these behaviors or avoid the circumstances where these behaviours happens paving the way for more advanced and reliable radio systems.
What you will do:
During this thesis work you have the opportunity to work with realistic data coming from our testbeds to study the actual hardware imperfections. The thesis work will be organized around one or two type of hardware imperfection. The end goal of the work is to develop one or more models and compare the performance of these models with the existing ones toward the following steps:
