Research Lab Information Theory Lab At the moment there are several research projects running, all of them centered around the analysis of the maximum amount of information that can be transmitted over a certain communication system, the so called capacity. Specifically, our research time is concentrated on the following questions: What are the fundamental limitations of wireless communication systems? What are the fundamental limitations of wireless optical communication systems? What are the fundamental limitations of wired optical communication systems? What is the high-SNR capacity of flat fading channels? In particular we are interested in the second term of the high-SNR asymptotic expansion of capacity, the fading number. How can we find approximations to the exact capacity using numerical methods and computer simulation or computation? How does the high-SNR capacity of flat fading channels change, if instead of several antennas at the transmitter we have several (independent) users with only one antenna? How sensitive our high-SNR capacity results to changes of the channel model?
