In this letter, we propose a novel decision-aided phase noise (PHN) compensation scheme for 60 GHz millimeter-wave single-carrier frequency-domain equalization (SC-FDE) systems. The proposed scheme works in an iterative manner. During each iteration, we first chop each received data block into several equilength sub-blocks, and use the data decision obtained from the previous iteration to estimate the PHN in each sub-block. Then we use the PHN estimate newly obtained to compensate for the PHN effect. Last, we conduct FDE and data decision for each received data block. With increasing iterations, the length of subblocks is gradually decreased, which leads to increasingly accurate PHN estimation and data decision. It is shown through simulations compliant with the IEEE 802.11ad standard that the proposed scheme outperforms the counterpart of similar complexity and can effectively alleviate the adverse effect of PHN.
