Aimed at the problem in the Kalman multiuser detector with a rapid performance degradation in the presence of signature waveform mismatch in the multipath channel, an improved blind multiuser detection algorithm is presented based on Kalman filtering. The method introduces the subspace technique to modify original state space model, thus the detector is modeled as a vector in the signal subspace.
