Piyush Yadav, Ratna Gour . Pilot Extraction for CFO Estimation using Comb-Type Pilot Arrangement. International Journal of Computer Applications. 94, 12 ( May 2014), 28-33. DOI=10.5120/16397-6016
Abstract
Frequency synchronization is vital issue in execution of OFDM system. In this paper we proposed a technique to estimate and compensate CFO in frequency domain. Estimation is based on Comb-type pilot sequence, which can measure phase rotation of received signal pass through fading channel. Performance of proposed scheme is evaluated on basis of MSE and BER. CFO estimation can be computed by pilot, phase information obtained at receiver side. It is estimated at receiver by fine CFO estimation.
