Behavioral Modeling Accuracy for RF Power Amplifier with Memory Effects
In this paper, a system level behavioural model for RF power amplifier, which exhibits memory effects, and based on multibranch system is proposed. When higher order terms are included, the memory polynomial model (MPM) exhibits numerical instabilities. A set of memory orthogonal polynomial model (OMPM) is introduced to alleviate the numerical instability problem associated to MPM model. A data...
متن کاملBehavioral modeling and linearization of a millimeter-wave power amplifier
The use of digital predistortion for linearizing a millimeter-wave power amplifier (PA) is investigated. A PA operating at 38 GHz is designed using an accurate non-quasi-static transistor model, taking into account both shortand long-term memory effects. A realistic test signal is then used for the identification of a nonlinear auto-regressive moving average (NARMA) behavioral model of the PA. ...
متن کاملPower Amplifier Modeling and Power Amplifier Predistortion in Ofdm System
This paper presents a baseband predistorter to be used in OFDM systems operating with a nonlinear high power amplifier (HPA). Key features of the predistorter reside in the use of the HPA inverse structure as nonlinear distortion compensator. The performance of the compensated system is analyzed by simulations in an AWGN environment. The receiver also needs furthermore an equalizer in order to ...

متن کاملMemoryless Non Linear Modeling of Power Amplifier
To ensure that linearity is maintained to a high degree, it is necessary to examine the nature of amplifier distortion. Audio amplifier distortion is of concern for many years. The conventional feedback techniques used at audio frequencies are not applicable to many RF amplifiers due to following problems: 1. Stability at high bandwidth; 2. Cost for high gains in RF stages. Memory less or Insta...
