Objective
Main Objective
The objective of the project is to develop innovative base station array processing architectures and algorithms for UMTS that are sufficiently flexible to support a range of different second and third generation air interface standards.
Technical Approach
This project builds on the work of TSUNAMI-II (AC020). It is based on conducting field trials of adaptive antennas, using prototype equipment in a real mobile network. The first few months define the project's requirements. Mobile operators' requirements and the groundwork of the architectural definitions, including the system design choices and algorithms suitable for W-CDMA, will be completed.
Experiments and simulations will be carried out to allow architectural decisions to be made and the top level system design to be performed. Propagation measurements will be conducted in Aalborg (Denmark) and will be focused on developing the channel models required for the Adaptive Antenna technology baseline architectures in a realistic deployment. In order to achieve all the beamforming capabilities, studies will based on the information pertaining to different air interface and the additional signalling needed to complete all the process. Important requirements set by Adaptive for the UMTS BSS, using the present wireless systems, are determined.
Joint multi-user detection techniques for the seamless incorporation into W-CDMA will be studied, and the maximum performance in terms of interference cancellation will be investigated.
Summary of Prototype
The project will undertake prototyping of adaptive array processing software radio modules on a real-time platform. The aim of this task is to assess the use of the software radio concept for the implementation of adaptive antenna in base stations. Accordingly, the prototyping will be based on high speed DSP and this work will form an integral part in the UMTS adaptive antenna base station. The results from various other activities will be compared to identify the roadmaps.
Expected Impact
Adaptive antennas and software radio technology will have an enormous impact on the economics of network infrastructure deployment. A network infrastructure which is not confined to a single air interface standard but can be readily reconfigured during its operational lifetime, or in response to short term demand to enhanced deployment.
Key Issues
Design and development of flexible Air Interface adaptive antenna systems is a major challenge towards the realisation of Smart Antennas for UMTS. Adaptive antennas are potentially invaluable technology and proven in a true mobile application. It is hoped that by incorporating the software radio concept, authoritative candidate architectures will be obtained to contribute to the roadmaps in the standardisation process of third generation systems in Europe in fora such as ETSI SMG5.
