摘要：
We proposed a new predistortion scheme that result in a fast convergence performance by using a gradual quantization on input signal value from rough to fine. We compare the performance or the proposed scheme to conventional methods. Simulation results of the OFDM system on an AWGN channel reveal that the proposed method show improved convergence performance without any loss in accuracy.
