Abstract :
In this paper, a variable forgetting factor RLS adaptive equalizer is proposed for direct sequence code division multiple access (DS-CDMA) communication system. We consider an adaptive Laguerre lattice equalizer which applies an optimal method based on the variable step-size least mean square (VSLMS) algorithm for adaptable forgetting factor RLS algorithm for improve performance of the receiver.
