Abstract

Transmission of wavelet-compressed still images using FFT-OFDM over multipath power line communication (PLC) channels under additive white Gaussian noise (AWGN) and impulsive noise is addressed. Only the low-subbands coefficients were chosen to be transmitted from each decomposition level for compression, rather than using a global threshold for the compression of the wavelet coefficients. A study of the number of paths and length of link have been carried out to observe their effect on the quality of image via structural similarity quality assessment.
