- Abstract
- Phase noise becomes a critical problem as wireless communication systems utilize high frequency band such as mmWave or THz. The effects of phase noise should be correctly estimated and compensated to achieve the required performance. In this paper, a linear MMSE based common phase error estimation algorithm is proposed under 3GPP NR DM-RS and PT-RS structure. It is shown that the proposed algorithm can estimate common phase error efficiently with reduced complexity.
