Abstract :
An improved adaptive algorithm combined with Least Mean Square (LMS) and Recursive Least Squares (RLS) algorithm is presented in this paper. Simulation results show that in comparison to the traditional algorithm, this joint method can not only achieve a satisfied linearization performance, but reduce the calculation amount and enhance convergence stability.
