Abstract :
Alpha stable distribution is better for modeling impulsive noises than Gaussian distribution in signal processing. We proposed a new adaptive recursive least p-norm Kalman filtering algorithm and a new robust CDMA multiuser detection method based on least p-norm Kalman filtering. The simulation experiments show that the proposed new algorithm is more robust than the conventional Kalman filtering
