Correlation based phase noise compensation in 60 GHz wireless systems

The necessity of phase noise (PN) compensation in future 60GHz communication systems is shown in this paper. Based on a reference hardware testbed we evaluate the impact of PN on the transmission performance. We show that long data transmissions can only be obtained with PN compensation even for low modulation orders. A low-complexity algorithm for phase noise estimation and compensation based on auto-correlation of pilot words is described. An efficient all-digital architecture for the proposed algorithm is presented.
