…and welcome to my website. My name is Alexander Nähring, I am 25 year old and currently enrolled as a student in Electrical Engineering, Information Technology and Computer Science at the RWTH Aachen University with focus on Communication Engineering.

Besides studying I like to code in my freetime.
My programming and coding skills reach from C/C++ and PureBasic over HTML5, CSS3, Javascript (& jQuery) to MySQL and PHP.

Furthermore, I am interested in books & movies, skiing, photography and tinkering.

Master of Science

Currently, I am working on my Master's Thesis at the German Aerospace Center in order to receive my Master's Degree from the RWTH Aachen University. My field of study is the adaptive interference mitigation in space-, time- and frequency domain. The results of this work will be used to implement modern receivers for global navigation satellite systems (like GPS or GALILEO) which will be more restiliant to interferences, spoofing and jamming as well as having better reception in suboptimal environments.

Bachelor of Science

In 2014, I completed my bachelor thesis in Electrical Engineering at iNETS, Institute for Networked Systems, RWTH Aachen University with the topic 'Empirical Characterization of a 60 GHz Transmission Link':

Wireless systems are integral part of modern day life. Nearly every household operates a Wireless Local Area Network (WLAN) router or at least other devices enabled with wireless communication. But while there is more and more demand for high more data rate, current wireless communication links reach their capacity limit. The current frequency bands useable for wireless communication are overcrowded, especially in urban areas.
The main goal of this thesis work is to characterize a 60 GHz short range communication link, which could potentially be a solution for satisfying the growing throughput demands. This thesis work provides a unique characterization of actual packet and frame based transmission. Besides private WLAN a reliable fast link communication could also be useable for secure Point-To-Point (PTP) communication or high speed interconnects in data centers. The 60 GHz band offers both the available bandwidth for high speed links and the characteristics for secure PTP communication. In this thesis work, two different setups were built to test, measure and characterize the throughput, Bit Error Rate (BER) and distance of a high-frequency communication link suitable for short range applications. Both setups make use of custom-made Orthogonal Frequency-Division Multiplexing (OFDM) schemes for evaluation under different circumstances. High data rates of over 1 Gbps while maintaining a low BER are easily achieved, even while using only small portions of the total available bandwidth. The applicability and effectiveness of OFDM for a 60 GHz communication link is discussed as well as how the disadvantages of using a high frequency affect the adequacy in different possible applications. This thesis evaluates 60 GHz links in different application scenarios with a focus on the use of OFDM for millimeter wave communication links.
