This paper is concerned with a new time-domain adaptive predistortion scheme for compensating nonlinearity of high power amplifiers (HPA). A Hammerstein model is adopted to approximate expression of the input-output nonlinear distortion of HPA by using complex polynomial series followed by linear dynamical distortion. According to the Hammerstein model structure, the compensation input to HPA is calculated in a real-time manner so that the linearization from the predistorter input to the HPA output can be attained even if the nonlinear input-output relation of HPA is uncertain and changeable. The effectiveness of the proposed adaptive scheme is validated in numerical simulations.
