Although 60 GHz millimeter wave (mm-Wave) systems employing OFDM can provide multi-Gbps data rate, the high level of phase noise (PN) of the mm-Wave transceivers induces inter-carrier interference (ICI) that degrades the performance of the OFDM systems. In the conventional method, the effects of PN can be well compensated by the iterative receiver processing; however, it has high complexity. In the previous work, we proposed a simple frequency domain ICI compensation, that linearly combines the channel equalized receive signals; however, it needs PN-robust channel estimation methods. In this paper we evaluate the proposed scheme with considering the channel estimation, and propose a PN-robust channel estimation method.
