This paper is concerned with a new time-domain modeling topology for signals which is applied to wideband power amplifiers. The memory effect will be shown using two-tone intermodulation distortion (IMD) measurement with different tone frequency spacing and power levels. The model is developed by using a memoryless nonlinearity followed by a dynamic LTI system (Hammerstein model) to consider the memory...
This paper represents a new adaptive method to model the nonlinearity of power amplifiers(PAs) with memory effects based on Wiener approach and also adaptive predistorter to counterbalance the AM/AM and AM/PM nonlinear effects of the transmitter power amplifier is proposed by Hammerstein approach. Finally we consider the effectiveness of proposed method on performance of OFDM signal as the wideband...
