| Abstract(in English) | In this paper, we propose a time-domain equalizer using a neural network without known training signals for OFDM systems without CP. By adjusting trainable parameters of the neural network to minimize the output energy, the proposed equalizer can suppress inter-symbol interference while the desired signal component is kept unchanged. Unlike the most existing machine learning-based schemes, the proposed equalizer using no known training signals can prevent frequency efficiency degradation due to the transmission of known training signals and inserting CP. Simulation results show that the proposed equalizer can train successfully without known training signals, and it is superior BER performance to the machine-learning-based previous equalizer and the linear MMSE equalizer. |
