【简　介】:Abstract—In orthogonal frequency-division multiplex (OFDM)
communications, the loss of orthogonality due to the carrier-frequency
offset must be compensated before discrete Fourier transform-based demodulation can be performed. This paper proposes a new carrier offset estimation technique for OFDM communications over a frequency-selective fading channel. We exploit the intrinsic structure information of OFDM signals to derive a carrier offset estimator that offers the accuracy of a super resolution subspace method, ESPRIT.
Index Terms—Equalizer, estimation, multicarrier modulation,multipath channels, radio receiver.

【简　介】:Abstract—In orthogonal frequency-division multiplexing
(OFDM) communications, carrier frequency offset must be estimated
and compensated at the receiver to maintain orthogonality.
In this paper, we examine the performance of a blind carrier
frequency offset estimation algorithm for OFDM communications.
Experiments were conducted on a system operating at close to 2
MBits/s. Insights obtained from these experiments provided the
motivation to explore the fundamental relationships between estimator
performance and multiple system parameters such as the
signal-to-noise ratio, number of data samples, frequency-selective
fading, and power loading.We examine the sensitivity of the blind
carrier frequency offset estimation algorithm using first-order
perturbation analysis. In particular, we derive a closed-form
expression for the mean square error of the carrier frequency
offset estimator and present tradeoff studies for the high-resolution
blind estimator performance. The analytical and simulation
studies are in good agreement with experimental results.
Index Terms—Communication system performance, estimation,
frequency-division multiplexing, frequency synchronization, mobile
communications, multipath channel testing, orthogonal frequency-
division multiplexing (OFDM), perturbation methods.
