Mm-wave 26 GHz Channel Characterization for Future Wireless Communications

Abstract

In this work, mm-wave 26 GHz channel characteristics are analyzed based on experimental channel measurements performed for both LOS and NLOS scenarios. Specifically, channel parameters like power delay profiles (PDPs), rms delay spread, path loss and shadow fading are analyzed. Results show that the LOS components dominant over other multipath components in this band. Rms delay spreads are larger in the LOS case than those in the NLOS case, as the LOS measurement positions are much further in the measurements. Radio wave propagates like in free space in LOS case, as the path loss exponent is quite close to free space value of 2. Shadow fading (in decibels) fits well with normal distributions. These results can provide useful information for the design of future wireless communication systems.
