Yes / 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 raised cosine 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.
