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

  2. 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 • Multiuser space-time coding and processing • 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. 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.
