Abstract
The SC-FDMA (single carrier-frequency division multiple access) is uplink standard of the 3GPP LTE (3rd generation partnership project long term evolution) mobile system. SC-FDMA has very low PAPR (peak to average power ratio) but is sensitive to the ICI (inter carrier interference) by phase noise. In this paper, we analyze the effect of phase noise considering the back-off amount of HPA (high power amplifier). And we propose the equalizer of advanced PNS (phase noise suppressing) algorithm to remove the ICI component effectively. The adaptive equalizer has similar form of SD-FDE (single carrier-frequency domain equalization) and the operation process based on PNS algorithm to remove the ICI component even in the IQ imbalance environment, which will be shown in the simulation results.
