Future 6G systems require high-capacity data transmission utilizing ultra-high frequency bands. However, this leads to communication performance degradation due to the high peak-to-average power ratio (PAPR) of OFDM waveforms and phase noise, which destroys the orthogonality between subcarriers. Existing mathematical algorithms have limitations in correcting phase noise accurately due to information loss from aliasing. In this paper, we propose a phase noise estimator for DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) utilizing transformer models and demonstrate superior performance compared to existing mathematical algorithms through simulation.
