Accurate Loop-delay Estimation Method in Digital Predistortion System

摘要：

Digital predistortion is an effective method to compensate for nonlinear distortion of power amplifier. In order to improve the linearization performance of digital predistortion, an accurate loop-delay estimation method is proposed. This method can overcome the impairment caused by the nonlinear distortion of power amplifier, and it has higher accuracy and lower computation complexity than the previous loop-delay estimation methods. Simulation results show the effectiveness and correctness of the proposed method.
