We investigate nonstationary disturbances in wireline and wireless systems. In wireline, we make us of the common-mode signal to cancel impulse noise from the differential mode or use the common mode to forecast error positions. In wireless, we model impulse noise on antenna arrays caused by ignition, electrical machines, MRI equipment, and alike. Furthermore, we

    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

  Our MIMO research focuses on the treatment of imperfect channel information and a possible realization of UEP properties just as in the case of multicarrier transmission.  We consider multi-user bit loading, multi-user hierarchical modulation, LDPC coded hierarchical modulation.

  In a joint project with life sciences, we investigate the communications and code properties of the DNA. Our share deals with reasoning of the codon/aminoacid encoding structure, the error-protection, and source coding properties, whereas Prof. Mushelishvili’s group concentrates more on the influences of the three dimensional orientation leading to analog control mechanisms in gene
