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: Yilun Zhang Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2016   Description: With increasing significance of wireless transmission, physical layer security becomes a challenging topic resulting from the Shannon’s limit. This work explores physical layer security from the aspect of information theory and discusses key generation and reconciliation by Slepian-Wolf coding and low-density

Student: Usama Nadeem Advisor: Prof. Dr.-Ing. Werner Henkel Dawit Nigatu Time frame: Spring 2016   Description: Bidirectional reading processes have been recently incorporated into the Lempel-Ziv family of lossless compression algorithms namely LZ-77, LZ-78 and LZW 84.  Bidirectional compression results in better compression ratios especially if the uncompressed data contains symmetric properties. In this work

As an alternative to Diffie Hellman’s key exchange protocol, physical layer key generation is discussed based on measurements of reciprocal channels. Due to statistically independent noise together with vector quantization, the keys might not be the same. Hence, the contribution discussed key reconciliation possibilities, either introducing guard bands or LDPC Slepian‐Wolf coding. We derive a
