Behavioral Modeling and Digital Predistortion of Radio Frequency Power Amplifiers (2018)
Abstract / truncated to 115 words
The radio frequency power amplifier (RF-PA) within a digital wireless transmitter is a critical component regarding both the energy consumption and the signal quality. Especially due to today's broadband multicarrier modulation methods that generate signals with high peak-to-average power ratio, it is very hard to construct RF-PAs that achieve good energy efficiency and fulfill the strict linearity requirements imposed by the standard. Because of this, the digital predistortion (DPD) of RF-PAs has become a key technique for implementing energy efficient, high data rate wireless transmitters. This thesis investigates theoretical foundations and practical methods for the behavioral modeling and DPD of RF-PAs. The main contributions are a semi-physical model of the joint linearity-efficiency characteristics of RF-PAs, ... toggle 23 keywordsbehavioral modeling – digital predistortion – radio frequency – power amplifier – wireless transmitter – digital enhancement – nonlinear signal processig – linearity – efficiency – baseband – passband – even-order – phase homogeneity – fourier series – volterra series – chebyshev transform – quasi-memoryless – crest factor reduction – dual-band – envelope-tracking – synchronization – wirtinger-calculus – wallis integrals
