Abstract

The performance of look-up table (LUT) predistortion system is analyzed and simulated, and three conclusions are gotten. The first is the system SNR increases with the increasing of the LUT length, and if the length of LUT increases doublely the SNR increases at least 6 dB. And the second is the system with weaker nonlinearity characteristic PA has better system SNR. And the third is if the input signal with the characteristic of higher occurrence probability of little signal, the system SNR is finer. These conclusions are helpful to design the suitable parameter of the LUT predistortion system.
