Abstract
Cell search is one of the most
challenging tasks in cellular systems. There
have been large efforts on the synchronization
problem in OFDM based cellular systems.
Conventional synchronization schemes,
however, still have problems in initial timing
acquisition and cell identification, requiring a
large cell search time. In this contribution, we
propose a novel three-step cell search scheme
with the use of a new preamble for OFDMbased
cellular systems. Simulation results
show that the proposed cell search scheme
can significantly reduce the mean cell search
time in multi-cell environment, while reducing
the computational complexity.
