Abstract
The conventional Fourier-based complex exponential carriers of a multicarri er system are replaced with orthonormal wavelets in order to reduce the int erference. The wavelets are derived from a multistage tree-structured Haar and Daubechies orthonormal quadrature mirror filter (QMF) bank. Compared wi th the conventional OFDM, it is found that these wavelets reduce the power of ISI and ICI.
