Short Bio

Christian Steffens received his Diploma degree in electrical and information engineering in July 2010 from the University of Bremen. His Diploma thesis was about 'Cooperation in OFDM-Based Relaying Systems'. In November 2010 he joined the Communication Systems Group where he is now working on his Ph.D. in the field of Sparse Signal Recovery and Wireless Sensor Networks. Furthermore, he is maintaining the Software Defined Radio laboratory for practical experiments.
