Performance Evaluation of OFDM Transmission Over Impulsive Noisy Channels
Overview The aim of this paper is to investigate the effect of impulsive noise on the performance of the OFDM system. The bit error rate performance results are provided by means of simulation. The effect of changing the number of carriers of the OFDM system, impulsivity of the noise, different relative power of impulsive noise as well as different impulse-shaping filters are investigated and are compared with the Additive White Gaussian Noise (AWGN) case. Results show that for large Signal-to-Noise Ratios (SNR), and particularly very impulsive noise the OFDM system with large number of carriers can cope with the impulsivity of the noise, and can improve the performance.
