Abstract
This paper discusses the effects of frequency offset on the performance of orthogonal frequency division multiplexing (OFDM) digital communications. In this paper we present maximum likelihood (ML) algorithm for the joint estimation of sampling frequency offset and carrier frequency offset in the OFDM systems using a repeated data symbol. The simulation results are also presented
