A estimativa do deslocamento de frequência é uma técnica importante no projeto de receptores de comunicações sem fio. Em muitas aplicações, o tom de frequência única amostrado é selecionado como símbolo/sequência de treinamento para sincronização de frequência. Sob esta suposição, a estimativa do deslocamento de frequência pode ser considerada como o problema da estimativa do deslocamento de frequência de portadora única. Nesta Carta é proposto um estimador aproximado de frequência de máxima verossimilhança. Este estimador é eficiente em SNRs moderados e altos. Comparado com outros estimadores, o estimador proposto é menos sensível ao limite de variância e oferece níveis viáveis de complexidade computacional. O estimador proposto é adequado para casos de deslocamento de alta frequência e aplicações de sincronização de frequência grosseira/fina.

Abstract: Frequency offset estimation is an important technique in receiver design of wireless communications. In many applications, sampled single frequency tone is selected as training symbol/sequence for frequency synchronization. Under this assumption, frequency offset estimation can be regarded as the problem of single carrier frequency offset estimation. In this Letter, an approximate maximum likelihood frequency estimator is proposed. This estimator is efficient at moderate and high SNR's. Compared with other estimators, the proposed estimator is less sensitive to the variance threshold and offers feasible levels of computation complexity. The proposed estimator is suitable for high frequency offset cases and coarse/fine frequency synchronization applications.
