| Abstract(in English) | High-accuracy wideband signal transmission is essential for 5G and Beyond wireless communication systems. Memory nonlinearity in a transmitter is a serious issue for the goal, because it deteriorates the quality of signal and reduces system performance. This report studies a post-reception nonlinear compensation (PRC) scheme consisting of frequency domain equalizer (FDE) and blind nonlinear compensator (BNLC). A Winner-Hammerstein model is employed as the transmitter memory nonlinearity model, and two PRC configurations with FDEs and BNLC are evaluated through computer simulations. It is concluded that the proposed PRC schemes can effectively compensate memory nonlinearity in the wideband transmitters via frequency-selective propagation channel. |
