Phase noise estimation in OFDM systems
Artikel i vetenskaplig tidskrift, 2024
In this paper, we present a comprehensive foundation for the theory and practice of pilot-based carrier phase synchronization of OFDM symbols in the presence of phase noise. The system covers phase noise added in both the transmitter and receiver together with a frequency-selective channel. A novel, low-complexity, phase noise estimation method is presented, and we show that it is close to optimal over a wide dynamic range of phase noise. Additionally, a method for approximating the phase noise over the OFDM symbol using principal component analysis is proposed, where the number of parameters to estimate can be significantly reduced with minimal impact on performance.
