Abstract:This paper introduces a novel channel and carrierafrequencyaoffset (CFO) estimation scheme for orthogonalafrequency-divisionamultiplexing (OFDM) transmission over time-varying channels. The proposed design is highly flexible and compatible with orthogonalamultipleaaccess (OMA) and non-orthogonalamultipleaaccess (NOMA) transmission. The new estimator performs the channel and CFO estimation jointly and blindly, highlighting the efficiency of the proposed estimator. The blind CFO and channel estimation are realiz… Show more
