A coefficients extraction algorithm for LUT-based Hammerstein predistorters
There are many digital baseband predistorters, which are used to overcome the nonlinearity and memory effect of power amplifier for wideband signals. Look-up table-based Hammerstein predistorter is one of them and has remarkable advantages comparing with the others. In this paper, an iterative algorithm is proposed for extracting the coefficients of the look-up table-based Hammerstein predistorter. An ADS simulation testbed is built to verify the predistorter and algorithm, and the simulation results demonstrate the good performance of our algorithm.
