A new blind adaptive multiuser detection scheme based on a hybrid of Kalman filter and

subspace estimation is proposed. It is shown that the detector can be expressed as an anchored

signal in the signal subspace and the coefficients can be estimated by the Kalman filter using only

the signature waveform and the timing of the desired user.-A new blind adaptive multiuser detection s cheme based on a hybrid of the Kalman filter and subs pace estimation is proposed.
