Abstract :
The paper develops adaptive step size blind LMS algorithms for code-aided suppression of multiple access interference (MAI) and narrow-band interference (NBI) in DS/CDMA systems. These algorithms optimally adapt the step size using the same measurements which are used for adapting the weight vector of the linear detector
