ABSTRACT A new coarse frequency offset estimation algorithm is proposed
which performs robust operation in the presence of a symbol timing
offset in an allowed range. The effect of a symbol timing offset on
estimating a coarse frequency offset is analyzed and the coherence phase
bandwidth according to the allowed symbol timing offset is introduced.
In addition, a new technique for performing the coarse frequency
estimation using the coherence phase bandwidth is described. Simulation
results show that the proposed algorithm estimates a coarse frequency
offset well under both AWGN and multipath channels even in the presence
of the symbol timing offset within an allowed range
