Abstract :
In this paper, the performance of adaptive feedforward systems based upon the dual loop and triple loop configurations are presented. Explicit equations, showing the interdependency between loop parameters such as the convergence rate and coefficient jitter, for a CDMA input signal are developed. Both theoretical and computer simulated results are included for comparison
