Work in xDSL focuses on problems of multicarrier transmission, like PAR reduction, time-domain equalization, bit-allocation. To name just a few outcomes of this research:    First real capacity optimizing time-domain equalizer    PAR reduction scheme which is widely used (many million installations)    A bit-allocation scheme allowing for arbitrary SNR margins between priority

Student: Ahmed Elshahed Advisor: Prof. Dr.-Ing. Werner Henkel Dr. Khodr Saaifan Time frame: Spring 2016         Description: In this thesis, we consider the interference cancellation problem for the broadband digital aeronautical communication system. We investigate the L-band digital aeronautical communication system (L-DACS) in the presence of distance measuring equipment (DME) interference. First,

Student: Zinan Liu Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2015           Description: This Guided Research focuses on frame synchronization for the DMT-based transmission system, which is used on a proposed acoustic sensor network for sonar applications. The time offset estimate not only needs to be robust and accurate to

Student:  Maja Taseska Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2010         Description: The combination of multicarrier modulation (OFDM, DMT) and Multiple- Input Multiple-Output (MIMO) transmission significantly improves the quality and efficiency of modern communication systems. The peak-toaverage ratio problem in multicarrier modulation requires additional transmitter side processing which may get

Student:  Oana Graur Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2009         Description: Impulse noise has long been known for causing transmission errors. The current thesis presents a method of mitigating impulse noise using a Normalized LMS canceler which takes as reference input the common mode signal and subtracts the adapted
