Digital predistortion of radio frequency power amplifiers using a Kautz-Volterra model
2006 (English)In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 42, no 13, 780-782 p.Article in journal (Refereed) Published
A digital predistortion algorithm for radio frequency power amplifiers based on orthonormal basis functions is presented. It has the same general properties as a Volterra model, but fewer parameters. Experimentally, using a 3.84 MHz wide signal at 2.14 GHz, the adjacent channel power was suppressed 12 to 15 dB, which was 5 to 7 dB more than a polynomial predistorter.
