Outline:

The European research project WINNER is a cooperation of 39 partners from industry, operators, and academia, which is partly funded by the European Union. It has the overall goal to develop a single radio interface covering the full range from isolated hot spots to wide area cellular scenarios by using different modes of a common technology. It targets increased data rates, low latency, and high system capacity based on adaptive transmission schemes, flexible spectrum usage, relaying, and advanced multi-antenna processing. The WINNER I project (2004-2005) evaluated technologies and combined them into a system concept. It forms the basis for the WINNER II project (2006-2007), which aims at the design and detailed assessment of a beyond 3G system proposal.

The WINNER radio interface design is aimed at attaining both high flexibility in terms of spectrum use and fulfillment of user requirements and a high spectral efficiency in different deployment and usage scenarios; two goals that are often contradictory and difficult to combine.

Abstract:

Abstract`Within the EU FP6 Integrated Projects WINNER and WINNER II, multiple access schemes for frequency-adaptive and non-frequency-adaptive transmission for a future broadband mobile wireless system are investigated.

This paper presents a novel power efficient multiple access scheme for non-frequency- adaptive uplink transmission denoted Block Interleaved Frequency Division Multiple Access (B-IFDMA), which provides large frequency-diversity, potential power savings by user terminal sleep mode, modest high power amplifier backoff and robustness to frequency offsets, and phase noise.
