Skills talk: Best Papers Michaelmas 2007

Each member of the group will submit an entry for the best paper they have read this term. We will have very a brief presentation on as many as we can fit in to 30 minutes.

Research talk: A primer on physical layer collaborative communication, Ioannis Chatzigeorgiou and Weisi Guo

In wireless communication networks, mutlipath fading is a severe impairment which can be mitigated through the use of diversity. Space diversity based on the use of multiple antennas can be readily combined with time and frequency diversity; however, the terminals may not be able to support multiple antennas due to physical constraints. An alternative means of transmit diversity is user cooperation, according to which each user “overhears” its partners and relays their data to the destination. In this talk we compare the performance of coded cooperation in a slow fading environment and discuss power allocation and partner selection schemes.
