Statistical Analysis of Multipath Clustering in an Indoor Office Environment

EURASIP Journal on Wireless Communications and Networking, 2011
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.
