Frequency Error Correction for OFDM based Multicarrier Systems and Performance Analysis

Sithamparanathan, Kandeepan; Reisenfeld, Sam


The presence of frequency offsets in the received signal for an orthogonal frequency division multiplexing (OFDM) based multicarrier system leads to inter carrier interferences (ICI). The degradation in the performance of an OFDM system is severe when there is frequency error, which is caused by the loss of orthogonality in the received carrier frequencies. Here, we look into the correction of frequency errors in the received OFDM signal, by means of a correlator based maximum likelihood (ML)...[Show more]
