Bondar, Dmytro and Budimir, Djuradj (2009) Digital baseband predistortion of wideband power amplifiers with improved memory effects. In: IEEE Radio and Wireless Symposium 2009 (RWS'2009), 19 - 22 Jan 2009, San Diego, California.Full text not available from this repository.
A new digital baseband predistortion of wideband power amplifiers with improved memory effects is presented and investigated. Distortion compensation is increased by implementing proposed iterative digital baseband injection technique. Frequency-domain equalization in baseband is developed to minimize memory effects. The non-linear and memory parts of the proposed linearizer are implemented in baseband without additional feedback loop. The spectral regrowth improvement of 20 dB for a 5-MHz 16-QAM signal and a 10 dB reduction of 8 MHz offset adjacent channel power ratio (ACPR) are achieved.
