Re: stds-80220-ch-models: MIMO channel modeling info sources
Hi Ken and all,
The contribution C802.20-03/42 that was presented in Dallas last month proposed
an approach for MIMO modeling that was also used in the development of a
system-wide spatial channel model in the 3GPP and 3GPP2 bodies recently.
The link to this document is:
This document could be used as a starting point in the discussions here. It also
provides some answers to the polarization modeling that resulted from analysis
of measurement data.
