In order to reduce channel noise, parameter mismatch, and cross talks in chaotic multi-user communication systems under a single channel, a feedback filter bank based on the square root unscented Kalman filter (SR-UKF) and its realization algorithm are proposed in this paper. The numerical simulation results indicate that the feedback SR-UKF (FSR-UKF) algorithm can effectively realize chaotic multi-user communications in a single channel, and is of a faster convergence speed than the recently reported alternative method..
