| Abstract: | This paper describes the implementation of FPGA-based memory polynomial predistorter.Firstly,the coefficients of memory polynomial are extracted by using LMS algorithm with indirect learning structure;Secondly,transform the form of polynomial to construct LUT-based predistortion unit;Finally,the top-level block diagram are represented and the effectiveness of the predistortion linearizers are demonstrated by experimental results obtained in a real platform. |
| Keywords: | Digital predistortion Non-linearity Memory effects Memory polynomial Power amplifier |
