Biografie

I completed my Bachelors Degree in electrical engineering and information technology in 2021 at TUM. I then pursued the consecutive Master program at TUM, where I focused on signal processing and communications engineering topics. During my time as a Master Student, I worked half a year full time at Huawei Munich Research Center in the Optical & Quantum Laboratory, where I then also subsequently did my Master's Thesis, where I performed theoretic and experimental physical layer investigations on a newly proposed fiber-to-the-room (FTTR) system architecture. After half a year abroad, I then returned to the Huawei Optical & Quantum Laboratory in February 2025, with which I am now doing my PhD. The PhD revolves again around FTTR topics and it is supervised by. Prof. Gerhard Kramer.

With current WLAN networks, generally a single user / station (STA) is only served by a single access point (AP). Whenever a STA moves from one coverage area to the next one, a handover between AP's on a higher level is performed. The same principle still generally holds for cellular networks, where each STA in the network is solely served by a single base station (BS). Generally, especially STA's at the edge of a cell (edge users) have significantly worse throughput compared to users closer to the cell center. Since these edge users are located close to the edge of one or multiple adjacent cells - in theory, they could significantly benefit by being jointly served by multiple BS instead of only a single one. However, in order for multiple BS to serve a single STA, coordination between these serving BS is necessary. This coordination comes with a overhead cost, because a significant amount of control and synchronization information between the BS have to be shared, a lot more channels have to be estimated and processing becomes generally significantly more complex. There has been quite some research effort regarding coordinated multi-point transmission (CoMP) systems with regards to cellular networks, however, due to the aforementioned overhead costs, increased complexity and costs, CoMP has not been standardized for cellular networks until now.

Fiber-to-the-room (FTTR) systems, as a new network architecture for WLAN networks, have gained increasing interest over the last years. With these FTTR systems, generally an increase of AP's with respect to the respective coverage area can be expected. Thus, in order to fully exploit the advantages that come with these newly emerging FTTR architectures and systems, CoMP transmission techniques are of interest. Additionally, due to the differences in user sizes, network architecture and backbone requirements for the systems, CoMP could in theory be an well suited approach for FTTR systems in order to increase data rates and reliability.

In my research and my PhD I investigate, whether and how CoMP techniques and approaches can improve FTTR network performance.
