For orthogonalfrequencydivisionmultiplexing (OFDM) communication systems, the frequency offset in mobile radio channels distort the orthogonality between sub-carriers, which results in intercarrierinterference (ICI) and seriously degrades the performance of systems.

OrthogonalFrequencyDivisionMultiplexing (OFDM) is an emerging multi-carrier modulation scheme, which has been

Inter-carrierinterference (ICI) reduction techniques achieve a better carrier-to-interference ratio (CIR) inOFDM system in the presence of synchronisation errors. However, the frequency diversity available on the frequency-selective channel...

Carrier frequency offset is the major problem associated with OFDM (OrthogonalFrequencyDivisionMultiplexing) systems as it causes the loss of orthogonality of sub-carriers & hence results into InterCarrierInterference (ICI).

interCarrierInterference (ICI) in OFDMdue to frequency offset by Krishna Sankar on August 8, 2009In this post, let us evaluate the impact of frequency offset resulting in InterCarrierInterference(ICI) while receiving an OFDM modulated symbol.

Abstract: This work quantifies, for the first time, intersymbol and intercarrierinterferences induced by very dispersive channels inOFDM systems. The resulting achievable data rate for \wam{suboptimal} OFDM transmissions is derived based on the computation of signal-to-interference-plus-noise ratio...
