| Abstract(in English) | Transmitters and receivers in 5G systems are required to cover broad bandwidth and achieve high-accuracy signal transmission. This paper proposes a novel blind nonlinear post-compensation technique that improves received EVM by eliminating whole nonlinearities caused by transmitter and receiver after receiving the signal. The total nonlinear characteristic is modelled using a tandem polynomial and the proposed post-compensator determines the inverse characteristic of the tandem nonlinearity without knowledge of sending signal. The simulation results employing LTE-A signal with 256 QAM modulation show that the proposed method can efficiently suppress nonlinearity and achieve EVM of less than 2.0 %. |
