Abstract
Wavelets are alternative building kernels of the
multicarrier systems, such as the orthogonal frequency division
multiplexing (OFDM). The wavelets can be designed by
changing the parent basis functions or constructing new filters.
Some two new wavelets are considered for multicarrier design;
one is designed using raised-cosine functions while the other
was constructed using ideal filters. The spectrums of raisedcosine
wavelet filters are controlled by a roll-off factor which
leads to many distorting sidelobes. The second family of
wavelet, which the raised-cosine wavelet is compared to, have
no distorting sidelobes. It will be shown that raised-cosine
wavelets are less suitable for multicarrier design in
multicarrier environment, in terms of BER when compared to
the wavelet constructed from the ideal filter.
