Digital Predistortion of Power Amplifiers for Wireless Applications
For my family. iii ACKNOWLEDGEMENTS It is time to draw a period to my PhD endeavor. I feel extremely lucky to meet so many talented people during these years. I am grateful for their friendship, help, encouragement, and support. First, I would like to thank my advisor, Dr. G. Tong Zhou, for providing this opportunity for me to study at Georgia Tech. Her constant encouragement and valuable advic...
متن کاملDigital Predistortion Techniques for Rf Power Amplifiers with Cdma Applications
With the increasing importance of spectral efficiency in mobile communications, linearity of the RF PA has become a critical design issue for non-constant-envelope digital modulation schemes.1 This issue is particularly significant in spread spectrum applications such as CDMA and wideband CDMA (W-CDMA) base stations, where the peak-to-average ratio of modulated RF signals can vary over a range ...

متن کاملDigital Predistortion for the Linearization of Power Amplifiers
High efficiency and linearity are indispensable requirements of power amplifiers. Unfortunately they are difficult to obtain simultaneously, since high efficiency PAs are nonlinear and linear PAs may have low efficiency. In order to satisfy the efficiency and linearity requirements, designers preferred to prioritize the efficiency of PAs in the design process and to later recover the linearity ...
