13 May 2005 SPW2- Dept. 1 Plenary Meeting

SummaryOne 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 Systems1.        Coding Design for OFDM and MIMO Systems2.        Signal Design for OFDM and MIMO Systems3. Multiuser space-time coding and processing4. 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.

OutputsAnalytic (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.
