Abstract :
An adaptive tapped delay line equalizer is described which operates in a DS-CDMA receiver. This structure, without modification, can be applied to make the system insensitive to spectral inefficiency of the transmitted pulse shape (by rejecting multiple-access noise), to act as a RAKE in the presence of multipath interference, and to reject narrowband interference. The latter property is the main focus of this paper; this technique is compared to previously published methods of narrowband noise rejection
