Abstract

This paper aims to characterize the ergodic capacity of multiple input
multiple output (MIMO) antenna beam-forming in indoor multi-path
propagation environments. Using Double Directional Cluster Ray (DDCR)
channel models, the second order statistics of the strongest eigen-mode
of the channel is analyzed. An upper bound on the ergodic capacity
of the MIMO beam-forming is derived and the impact of channel propagation
parameters, such as cluster/ray arrival rates and power decay profiles,
on the ergodic capacity is investigated. The theoretical results
are subsequently applied to estimate the capacity of the next generation
very high throughput WLAN at the 60 GHz frequency band.
