Channel Characterization of Ultra Massive MIMO Systems Utilizing Millimeter Waves For 6G Vehicular Communication

The characteristics of ultra-massive MIMO (UM-MIMO) systems that apply millimeter waves for 6G vehicular communication functions is evaluated in this work. This paper investigates path gain and root mean square delay spread together with path loss exponent across an indoor office space at 60 GHz through Wireless InSite (WI) 3D modeling in combination with Matlab-based ray tracing simulation techniques. The research reveals path gain values show substantial changes as a result of multipath propagation together with material properties and antenna configurations which affect signal behavior based on transmitter placement within the environment. With RMS delay spread analysis high-gain antennas prove vital in reducing the extent of channel dispersion. The research proved coverage predictions by combining statistical models and ray-tracing simulations which matched analytical results closely. The study generates essential knowledge to improve UM-MIMO deployment in future vehicular networks because it advances network functionality while strengthening complex communication stability.
