Space-Time Dense Multipath Components Modeling at mmWaves in Indoor Industrial Environments

This paper presents the characterization and models of specular and dense multipath components in the millimeter wave channels for industrial scenarios. The results are obtained from measurements covering the 26 - 30 GHz bands and employing a massive virtual array. Two different high-resolution algorithms, SAGE and RiMAX, have been employed. Then, a beamforming on the dense component is performed to obtain their angular distribution. The results are compared in terms of large-scale parameter fitting.
