Open publisher page 0 citations

Abstract

In this paper an algorithm of symbol synchronization and frequency offset estimation for OFDM based on the cost function is proposed. The algorithm is derived from a cost function, which is based on the character of the OFDM signal frame structure. Theoretical analysis shows that the symbol synchronization is independent from the frequency offset estimation when frequency offset exists. The simulation results indicate that the proposed algorithm has good performance.
