Abstract

This work presents measurement results and characterization of a wideband radio channel at 60 GHz in an indoor environment. Time delay values are evaluated while the coherence bandwidth of the channel is derived by the frequency correlation function. The mean excess delay ranges from 1.13 to 29.26 ns and the rms delay spread from 4.28 to 35.92 ns for the entire laboratory environment. The coherence bandwidth of the channel yielded for 0.9-correlation varies from 3.77 to 49.37 MHz with a mean value of 19.08 MHz.
