Abstract :
This paper presents pilot aided decision directed approach to estimate Rayleigh fading channel in direct sequence code division multiple access (DS-CDMA) RAKE receivers. The algorithm is tested with different models of the mobile environment. Simulation results are evaluated against ideal estimates and the estimates obtained by conventional interpolation
