Abstract
Cell search is one of the most important issues in
cellular systems. There have been large efforts on the
synchronization problem in OFDM systems. However,
conventional OFDM-based cellular schemes may have
problems in initial timing acquisition and cell identification,
requiring a large cell search time. In this paper, we propose a
novel three-step cell search scheme using a new preamble for
OFDM-based cellular systems. Simulation results show that the
proposed cell search scheme can provide fast cell search
performance in multi-cell environment, while reducing the
computational complexity.
