Isi artikel

The subchannel used for transmission in multicarrier system, is chosen to be orthogonal, so we can arrange subchanel in overlap condition. Orthogonal condition can be performed by a Inverse Wavelet Transform (IWT). Accordingly in the receiver we only need a Wavelet Transform (WT) to reverse this operation. Multicarrier system with overlap condition take smaller bandwith than non orthogonal multicarrier system. Orthogonal multicarrier system with wavelet was simulated in CDMA.
