Abstract
To solve the problem of memory nonlinear distortion in wideband OFDM system, a novel Frequency Domain Predistorter (FDPD) structure is proposed. The Predistorter which based on 2-dimension look-up table method is used in frequency domain. It can compensate the memory nonlinear distortion accurately, but the system performance is restricted by the size of lookup table. Then the Filter Look-Up Table (FLUT) with FDPD, which combined the FDPD with FLUT, is proposed to improve the BER performance and convergence speed. The simulation results indicate that the novel structure can decrease the BER in the receiver and increase the convergence speed.
