Abstract (in Japanese) (See Japanese page) 
(in English) In wireless communication complying with the regulation, very high frequency called millimeter wave band is assigned for TV network in indoor environment. As millimeter wave circuits nowadays can be manufactured by CMOS technology, communication using millimeter wave is attracted and standardized in IEEE802.15.3c. However mass production of the circuits becomes difficult as the characteristics of the local oscillator(LO) at millimeter wave band are no more as good as that of the conventional ones. Therefore, LO with large phase noise must be used. Phase noise causes ICI because of the destruction of orthogonality in OFDM system. We show the resulted error floor analytically, and confirm this performance by numerical simulation. This paper aims to improve this performance by digital signal processing, assuming a LO output spectrum following Lorentz model. Then, we propose a new algorithm which can alleviate the degradation due to phase noise but overcome the problem of halving the spectral efficiency in conventional self cancellation method. Finally, we confirm its effectiveness in parallel SISO system.
