| Abstract(in English) | The paper considers a pre-distortion method for frequency domain equalization (FDE) systems in order to achieve the improvement of the robustness against the phase noise. In the proposed method, we employ only a phase rotation at each subcarrier as the pre-distortion so as not to induce noise enhancement at the FDE in the receiver. As the design criterion of the phase rotation, we propose to use the entropy of the probability mass function (PMF), where each probability mass is defined by square of the coefficient of the corresponding impulse response of the pre-distortion. We prove that the maximum entropy can be achieved with the phase rotation only by showing a concrete example of phase rotation. Computer simulation results show that the proposed pre-phase rotation can improve the robustness against the phase noise in terms of bit error rate (BER) performance. |
