Abstract
Existing multiuser code-division multiple-access(CDMA) detectors either have to rely on strict power controlor near-perfect parameter estimation for reliable operation.In this paper, a novel adaptive multiuser CDMA detectorstructure is introduced. Using either an extended Kalman filter(EKF) or a recursive least squares (RLS) formulation, adaptivealgorithms which jointly estimate the transmitted bits of eachuser and individual amplitudes and time delays may be derived.The proposed...Keywords
