Millimeter-Wave Channel Characterization in Large Hall Scenario at the 10 and 28 GHz Bands

This paper presents the characteristics of the mm-wave propagation channel in hall scenario at the frequency bands of 9-11 GHz and 27-29 GHz. The spherical propagation parameters, i.e. delay, azimuth, elevation, source distance and complex amplitude are estimated by the high resolution parameter estimation (HRPE) algorithm. Based on the results, the channel characteristics, e.g. path loss, delay spread, and angle spread are analyzed for different mm-wave bands. The results reveal that the line of sight and specular components are dominant in such large size scenario at 9-11 GHz and 27-29 GHz bands, and little differences in the characteristics between the two bands can be observed.
