TLDR
Simulation results show that this co-ordinate interleaving technique enhances system performance without reducing the system rate.Abstract:
We study the use of co-ordinate interleaving technique for reducing the effect of frequency offset in OFDM communication systems. The inter-carrier interference effect (ICI) due to frequency offset is reduced by increasing the carrier power using CI techniques. The performance of OFDM with co-ordinate interleaving is compared with the conventional coding technique for combating the frequency offset. Simulation results show that this interleaving technique enhances system performance without reducing the system rate.read more

TL;DR: Simulations show that OFDM systems using the proposed ICI self-cancellation scheme perform much better than standard systems while having the same bandwidth efficiency in multipath mobile radio channels with large Doppler frequencies.

Intercarrier interference compression in OFDM communication systems by using correlative coding
TL;DR: Frequency-domain correlative coding with correlation polynomial F(D)=1-D in OFDM mobile communication systems to compress the intercarrier interference caused by channel frequency errors shows that such a simple coding method enhances system CIR by 3.5 dB, without reducing the bandwidth efficiency.

An improved ICI reduction method in OFDM communication system
TL;DR: In the OFDM system with phase noise, the data-conjugate method can make remarkable improvement of the BER performance and it is better than theData-conversion method and the original OFDM with or without convolution coding.
