Abstract :
The millimeter wave band is emerging as a promising choice for wireless communication systems for indoor environments. The 30 GHz frequency range offers higher bandwidth for higher data rates. This frequency also opens up capability for multiple antennas on mobile units. In this work, we explore the small-scale indoor propagation channel fading characteristics in the 30 GHz range using directional antennas. An experimental setup has been developed to measure the statistical characteristics of the signal. Data processing methods have been developed to compute the cumulative distribution function (CDF) from the measured data. The measured CDF is compared to Rician and Nakagami distribution models. This work explores how the model coefficients change over a small frequency range.
