Participating in Workpackage 5 - Multiple Antenna System for UWB

The promising UWB radio technologies, via taking advantages of free licensed UWB spectrum, significantly promote the short-distance wireless communication in data rate and the direction and location determination in accuracy. Meanwhile the additional multiple antenna technologies further improve both in innovative ways.

UWB multiple antenna system (MAS) has two different types:

UWB-MAS ~ Type A: Systems with a number of co-located antennas at the transmitter and receiver to achieve capacity and link reliablibity improvements for very high data rate applications.

UWB-MAS ~ Type B: Systems with distributed antennas located at several mutually cooperating nodes to achieve macro diversity and consequently link reliability improvements for low data rate applications, which comprise location, tracking, multi-hop and multi-path links.

Imperial College participates in this workpackage, particularly focusing on the UWB-MAS Type B.

Leading research in Task 5.1 - UWB-MAS Relaying and Network Coding Strategies

For the UWB-MAS Type B, i.e. the cooperative multi-antenna UWB wireless networks, cooperative transmission strategies are crucial for the improvements in capacity, diversity, as well as accuracy in applications.

Cooperative transmission strategies are realized via viable protocols, including ones in physical layer and network layer.

Imperial College is mainly concentrating on cross-layer protocol design for such cooperative multi-antenna UWB wireless networks.

Cross-layer protocol design for cooperative transmission strategies

In many network scenarios, centralized and synchronized cooperative transmission is not feasible. Researchers from Imperial College will investigate the design of viable protocols by taking into account of distributed implementation, non-synchoronous situation as well as cross-layer optimization.
