Measurement on 2.3GHz wideband indoor MIMO channel based on dual polarization antennas

This paper describes a newly-built broadband multiple input, multiple output (MIMO) channel characterization platform in indoor environment. The platform has been designed for measuring the S21 parameter between M transmitters and N receivers (M<;=8, N<;=8), which enables us to analyze the capacity and the directional multipath of the radio propagation channel. Data has been collected within a band varying from 2.2 GHz to 2.4 GHz inside a typical modern building with 8 transmitting antennas and 4 receiving antennas. Capacity results from these experiments are discussed for different propagation conditions, including none line-of-sight (NLOS), obstructed Line-of-Sight (OLOS) and line-of-sight (LOS) propagations with various spacing diversities and polarization diversities between array elements.
