Query: Multiresolution Division Multiplex (MRDM): A New Wavelet-based Multiplex
  System   An original multiplex scheme is introduced, which is based on Mallat's
multiresolution formulation of wavelet systems. 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 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.
