Student:  Alexandra Filip Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Fall 2012         Description: Key reconciliation procedures are needed to correct key differences that can arise as a consequence of independent noise at the two ends of a reciprocal link. We assume a line-of-sight channel and use reconfigurable antenna elements to randomize

Student:  Alexandra Filip Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Spring 2012         Description: Physical-layer key generation makes use of the reciprocity of wireless time-division duplex (TDD) channels. Both transmission directions experience the same channel, apart from independent noise and quantization effects. The randomness of a mobile channel ensures a certain regeneration

Student:  Alexandra Filip Advisor: Prof. Dr.-Ing. Werner Henkel, Dr. Mathias Bode Time frame: Spring 2013         Description: Physical-layer security in wireless communication is a challenging topic needed to allow for secure and reliable information transfer, otherwise subject to eavesdropping. In particular, physical-layer key generation methods use the properties of the channel itself

Student:  Alexandra Filip Advisor: Prof. Dr.-Ing. Werner Henkel Time frame: Fall 2011         Description: We propose a linear programming approach to optimize the variable node degree distribution for a Low-Density Parity-Check code that will provide UEP inside a modulation symbol. Based on a rate maximization criterion, the optimization of the degree distribution
