Abstract

The aim of this paper is to investigate the effect of impulsive noise on the performance of the WPDM (Wavelet Packet Division Multiplexing) system. The employed model of impulsive noise consists of Bernoulli distributed impulsive arrivals and Gaussian distributed amplitudes of the impulses. The effect of changing impulsivity of noise and different relative power of impulsive noise are investigated and are compared with Additive White Gaussian Noise (AWGN) case. Also, the performance of a WPDM is compared with single carrier system.
The results show that wavelet transform is sensitive to impulsive noise and increase number of subcarriers effect badly on the performance system. Two regions are founded comparing with single carrier system, the first region in which the performance of single carries system is better than WPDM system when SNR smaller than 15 dB. The second region in which the performance of WPDM system is better than single carrier when SNR higher than 15 dB.
