Abstract

Abstract:

In view of the problem of poor carrier frequency offset estimation performance over multipath channels for orthogonal frequency division multiplexing(OFDM) systems in non-cooperative communication, a new blind carrier frequency offset(CFO) estimation method is proposed. Firstly, the cost function based on the difference in amplitude is proposed. Secondly, the terminal cost function is derived by the product of the adjacent subcarrier's amplitude. Finally, the CFO estimation based on the polynomial interpolation is realized by the transformation cost function. Simulations show that the proposed CFO estimation method has a better performance and lower computational complexity over the multipath channels.

Key words: orthogonal frequency division multiplexing, carrier frequency offset, blind estimation, polynomial interpolation, multipath channels
