WebDigital predistortion (DPD) is the linearization technique most-often used nowadays to cope with the inherent trade- off between linearity and efficiency in power amplifiers (PA). Adaptation is needed to optimize DPD performance. This paper reviews strategies for estimating the parameters controlling the digital predistortion linearizer. WebThe increasing complexity of modulation schemes brought on by the evolution of mobile communication standards has led to high peak to average power ratio (PAPR) signals. As a result, traditional linear power amplifier (PA) architectures are no longer suitable as they exhibit low average efficiency when operating with such signals.
