This system is adaptable and its implementation is well matched to digital signal processors and computers. The approach termed multiresolution division multiplex (MRDM) is intensive in signal processing (SP) tools, extremely flexible and can combine a variety of tributaries at different bit rates. A broad variety of orthogonal wavelet systems {phik,psik,j} can endow with MRDM and the channel waveforms, and consequently the spectral shape and system performance depend upon the selected wavelets. Demultiplex can be done efficiently, since the number of floating multiplications and additions increase only linearly with the length of signals. A Haar-based MRDM scheme is presented to illustrate the versatility of this new multiplex approach.

The source bit stream is translated into a sequence of scales indicating which version of the mother wavelet should be transmitted in each symbol slot. The modulated signal therefore consists in a sequence of overlapping (or non-overlapping) scaled-translated versions of a wavelet. Such schemes can be viewed as a generalisation of "wavelet-based OFDM systems". Simple examples of deO-modulation and Mexican hat modulation are presented.

The codongrams and a2grams are offered as an alternative to spectrograms and scalograms. Twenty different a2grams are defined for a genome, one for each amino acid (valgram is an a2gram for valine; alagram is an a2gram for alanine and so on). They provide information about the distribution and occurrence of the investigated amino acid. In particular, the metgram can be used to find out potential start position of genes within a genome. This approach can help implementing a new diagnosis test for genetic diseases by providing a type of DNA-medical imaging.
