Abstract :
A network of Kalman filters (NKF)-based detector has recently been proposed for multiple access interference (MAI) and inter-symbols interference (ISl) compensation in DS-CDMA systems (B. Sayadi and S. Marcos, 2002). This paper presents a new structure, based on the NKF detector and on a Bayes-test for impulses localization. The resulting structure works efficiently in an "e-contaminated" noise environment. Their BER performance is near the Gaussian channel case.
