1. 13 May 2005SPW2- Dept. 1 Plenary Meeting SPW2- Signal Processing for MIMO Systems Xavier Mestre xavier.mestre@cttc.es Ana Pérez Neira anuska@gps.tsc.upc.edu

2. 13 May 2005SPW2- Dept. 1 Plenary Meeting Summary One of the recent “revolutions” in the Signal Processing for Communications area was the emergence of multi-antenna communications, both at the transmitter and receiver sides. Expectations are both in increased capacity and realiability. Former Activity cluster 2 of Dept 1: Signal Processing for MIMO Systems 1. Coding Design for OFDM and MIMO Systems 2. Signal Design for OFDM and MIMO Systems 3. Multiuser space-time coding and processing 4. Study of receivers schemes and channel estimation The former activities of NEWCOM on these topics will be expanded in order to address: -cooperative diversity, -virtual MIMO (macrodiversity), -Phy layer aspects of relay and mesh networks.

3. 13 May 2005SPW2- Dept. 1 Plenary Meeting Outputs Analytic (T1 + 12) : - Unified view of all space-time coding & processing schemes flexible MIMO architectures, guidelines for parameter design - Signal design: PAR, pulse shape desing - Special emphasis on time-varying channels - Multiuser case: rendering transparent the various trade-offs in resource allocation, multi-user efficiency Demonstrable (T1 + 18) : - develop workable & robust linear precoding schemes, - adaptive codeword generation, - resource allocation with and without feedback, and - low complexity detection schemes.
