Abstract

In this paper an adaptive equalizer using Laguerre transversal Alter and a RLS algorithm for adaptation in DS-CDMA mobile communication system is proposed. The stability of the Laguerre structure is compromise between the FIR and IIR structures, since the Laguerre structure is always stable. We also analyze the Bit Error Rate (BER) performance of the proposed equalizer and the conventional equalizer. The simulation results confirm that the performance of the proposed system in terms of bit error rate has been improved over the conventional equalizer, such as fast convergence and lower BER than the conventional adaptive equalizer for every Eb / No value. © 2008 IEEE.
