摘要：The steeping chip weighting waveforms are used in multiple access interference
cancellation by emphasizing the received spreading signal, therefore, that allows to
solve the problem of orthogonality for the chip waveforms. Our paper presents a useful
method based on fuzzy systems to determine the despreading sequences weighted by the
steeping chip weighting waveforms for Direct Sequence Code Division Multiple Access
DS/CDMA. The validity of our proposed method has been tested by numerical examples
for an Additive White Gaussian Noise channels and shows that the parameter values of
the chip weighting waveforms are good and the Bit Error Rate performance of the
system does not undergone any degradation.
