Article Ecrit par: De Lamarer, odrigo C. ; Sampaio Neto, Raimundo ;
Résumé: In this letter we investigate adaptive minimum bit error rate (BER) decision feedback multiuser receivers for DS-CDMA systems in fast frequency selective Rayleigh fading channels. We examine stochastic gradient adaptive algorithms and introduce fast algorithms for minimizing the BER cost function from training data.
