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`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
