Joint Estimation of Frequency Offset and Channel Frequency Response Using EM Algorithm for OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) systems are very sensitive to the frequency offset of the local oscillator at the receiver while the symbol timing offset can be absorbed in the guard interval. For the same reason, estimation of the ...
Multiple carrier frequency offsets tracking in co‐operative space‐frequency block‐coded orthogonal frequency division multiplexing systems
This study addresses the problem of carrier frequency offset (CFO) tracking in co‐operative space‐frequency block‐coded orthogonal frequency division multiplexing (OFDM) systems with multiple CFOs. Considering that the inserted pilot tones are decayed by ...
A time-frequency decision-feedback loop for carrier frequency offset tracking in OFDM systems
Acquisition and tracking are two crucial stages necessary to the carrier frequency synchronization in orthogonal frequency division multiplexing (OFDM) systems. In this letter, by employing the rotation property of OFDM data subcarriers, a simple time-...
