Li Changyuan1, Huang Tao1, Liu Yongpiao1, et al. Study on digital predistortion technology for power amplifiers[J]. 2010,(6):51-53. DOI: 10.13756/j.gtxyj.2010.06.002.
RF power amplifiers are subject to electric and thermal memory effects
resulting in spectral regrowth and adjacent channel interference
which cannot be cancelled by conventional memoryless predistortion technologies for the desired linearizing effects.For those memory power amplifiers
a novel memory polynomial predistortor is presented for those memory power amplifiers so as to track the variations of their characteristics and compensate the nonlinearity.
