Ultra-wideband statistical channel model for non line of sight millimeter-wave urban channels

This paper presents ultra-wideband statistical spatial and omnidirectional channel models for 28 GHz millimeter-wave cellular dense urban Non-Line of Sight (NLOS) environments, developed from wideband measurements in New York City that used synthesized timing from 3D ray-tracing. An accurate 3GPP-like channel model has been developed, where model parameters are based on empirical distributions for time cluster and spatial (lobe) channel parameters. A statistical simulator capable of reproducing the joint temporal and spatial measured channel statistics is given here. A step-by-step procedure for generating channel coefficients is shown to validate measured statistics from 28 GHz field measurements, thus validating our statistical channel model, for use in standard bodies and system-level simulations for millimeter-wave wideband communications.
