Abstract :
In DAB, a coarse frequency offset estimation algorithm has to provide an initial frequency error estimate, which is sufficiently accurate for the subsequent fine frequency synchronization algorithm to operate reliably. We present a coarse frequency offset estimation technique using the minimum energy detection scheme for an OFDM-based transmission system. It has been shown that the proposed algorithm has high robustness against a large range of symbol timing offsets with a low complexity.
