—We venture beyond the “listen-before-talk” strategy that is common in many traditional cognitive radio access schemes. We exploit the bi-directional nature of most primary c...
In this paper, we look at the time complexity of two agreement problems in networks of oblivious mobile robots, namely, at the gathering and scattering problems. Given a set of ro...
We consider the problem of multi-cell downlink beamforming with N cells and K terminals per cell. Cooperation among base stations (BSs) has been found to increase the system throug...
The question how to integrate information from different sources in speech decoding is still only partially solved (layered architecture versus integrated search). We investigate t...
: The performance potential of multistatic sonar operations has been investigated by several research institutes and proven in numerous international sea trials during the last yea...
