| Abstract: | By using estimated value from two-step least squares as the initial value of Taylor series expansion, the simulation and performance test were conducted in WCDMA environments. The results show that the proposed algorithm has higher accuracy than that of two-step least squares, approaching the result obtained from Taylor series expansion method. It has a great value in 3G mobile communications. |
