A Phase Noise Immune Equalization Algorithm For Millimeter Wave SC-FDE System

To solve the problem that phase noise affection of high-order modulation in millimeter wave broadband system, this paper analyzes and modifies the theoretical model of phase noise provided in the 802.11ad and 802.15.3c standards, and generates the actual noise values based on the modified model for simulation analysis. The frame structure given in standards is optimized for SC-FDE system to estimate noise and channel state by adding data block 0. An improved MMSE equalization algorithm is proposed in this paper to track the channel and phase noise changes in real time and obvious phase noise immunity characteristic is obtained compared with traditional algorithm.
