Abstract: In this work, indoor channel parameters and correlation properties are studied based on experimental measurements performed at 60 GHz in typical corridors for both line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios. Specifically, channel parameters like number of paths, root mean square(RMS) delay spread, Rician K-factor, and shadow fading are extracted from measurement data, and parameter distributions are analyzed further. Channel parameter correlation properties are also studied. Results show that in the LOS corridor channel parameters are highly correlated, in the NLOS corridor only RMS delay spread and number of paths are correlated highly. The excellent correlation property can provide useful information in predicting channel parameters from one another for design of 60 GHz wireless communications systems.
