Abstract :
In the literature, it has been demonstrated that applying a low complexity interleaving after the inverse fast Fourier transform (IFFT) in orthogonal frequency division multiplexing (OFDM) systems can significantly reduce the impact of impulsive noise [1]. The interleaving process introduces time diversity, which can be used to effectively combat impairments such as impulsive noise. However, the performance of the interleaving system is evaluated via Monte Carlo simulation. Therefore, this work considers the analytical performance evaluation of the post IFFT interleaving in impulsive noise channels, where a closed form formulae is derived for the system signal-to-interference and noise (SINR) and bit error rate (HER).
