In this paper

we employ wavelet networks for demodulation of DS-CDMA(direct sequence-code disivion multiple access) signals in a multi-access environment.In practice

conventional detector (single-user matched filter) suffers severe performance degradation as the relative powers of interfering signals become large.On the basis of MMSE(Minimum Mean-Square Error) linear detector we use adaptive wavelet network to achieve minimum mean square error

and effectively eliminate multi-access interference.Simulations show the detector based on wavelet networks can converge rapidly and is near-far resistant.
