Statistical Analysis of Multipath Clustering in an Indoor Office Environment

Free registration required

Executive Summary

A parametric directional-based MIMO channel model is presented which takes multipath clustering into account. The directional propagation path parameters include Azimuth of Arrival (AoA), Azimuth of Departure (AoD), delay, and power. MIMO measurements are carried out in an indoor office environment using the virtual antenna array method with a vector network analyzer. Propagation paths are extracted using a joint 5D ESPRIT algorithm and are automatically clustered with the K power-means algorithm. This paper focuses on the statistical treatment of the propagation parameters within individual clusters (intracluster statistics) and the change in these parameters from one cluster to another (intercluster statistics).
