A multiwavelets-based code-division multiple-access (MW-CDMA) scheme is presented based on the application of recent results in multiwavelet filter

preprocessing and balancing to communications area.In MW-CDMA

at first

the received signal is decomposed into the components in the orthogonal wavelet spaces

and then the multiuser demodulation is implemented in each wavelet spaces.Theoretical analysis and experimental results show that MW-CDMA systems suppress multiple-access interference and ambient noise well.Moreover

the scheme gives a new guidline of thought to reduce the computation for demodulation.
