| contents | This study introduces a Block Phase Tracking Reference Signal (PTRS) allocation approach for Discrete Fourier Transform-spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) systems to enhance phase noise tracking and compensation. Our proposed block allocation methodology leverages the concepts of multiresolution time-frequency tiling for more effective sampling, thereby mitigating aliasing effects and improving phase noise resilience. A key contribution of our approach is a novel modulation and demodulation scheme, incorporating a dedicated DFT-s-OFDM symbol, a modulator branch for block PTRS generation, and a dedicated demodulator for accurate phase noise estimation and correction. |
