It also causes distortions within the signal bandwidth. In this paper, we study five digital predistortion algorithms for linearising two different non-linear memory power amplifier models. The simulation results show that the proposed digital predistorter using different algorithms can improve the in-band distortion and out of band spreading in different ways. In particular, the DLMS algorithm with fast convergence can significantly suppress spectral regrowth (by 60dB), effectively compensating for the non-linearity of the power amplifier.<\/jats:p>","DOI":"10.1017\/s0960129513000698","type":"journal-article","created":{"date-parts":[[2014,9,5]],"date-time":"2014-09-05T00:08:51Z","timestamp":1409875731000},"source":"Crossref","is-referenced-by-count":0,"title":["Research on digital predistortion based on adaptive algorithms"],"prefix":"10.1017","volume":"24","author":[{"given":"JING","family":"DAI","sequence":"first","affiliation":[]},{"given":"RUI","family":"ZHOU","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2014,9,4]]},"reference":[{"key":"S0960129513000698_ref8","first-page":"1728","article-title":"A New Look-Up-Table Predistorter for Power Amplifier with Memory Effects.","volume":"36","author":"Zhang","year":"2008","journal-title":"Acta Electronica Sinica"},{"key":"S0960129513000698_ref4","first-page":"41","article-title":"Research on the Adaptive Digital Pre-Distortion Technique Based on the LMS Algorithm.","volume":"2","author":"He","year":"2010","journal-title":"Space Electronic Technology"},{"key":"S0960129513000698_ref1","first-page":"59","article-title":"High speed adaptive DLMS algorithm and its hardware implementation.","volume":"10","author":"Chen","year":"2007","journal-title":"Information Technology"},{"key":"S0960129513000698_ref2","unstructured":"Ding L.
