The 2×2 MIMO channel capacity is studied for millimeter wave radio propagation between two stations (STA-STA) on a table in a conference room. It is focused on whether a small antenna spacing enables a high MIMO channel capacity or not. The effect of reflection is also investigated on the MIMO channel capacity. For reflection, both two cases are considered: the reflection without scattering (where...
Distributed antenna systems (DAS) has been adopted in both indoor and outdoor wireless communications for benefits of reducing the power consumption and enhancing system capacity owing to spatial multiplexing gains. The capacity of a DAS system is partially determined by the cross-correlation of the large-scale fading of multiple links in the system. In this contribution, we use experimental data...
This paper aims at the eigenvalue analysis and its modeling for 2??2 (i.e., 2 transmit and 2 receive antennas) Multiple Input Multiple Output (MIMO) channel capacity based on Non Line-Of-Sight (NLOS) wideband indoor measurements. Our channel sounding system is the portable Band Exploration and Channel Sounding (pBECS) System, which works at a carrier frequency of 2.58GHz with 20MHz bandwidth. From...
This paper presents results of continuous wave and swept frequency response measurements over the frequency range of U-NII lower and middle bands from 5.15GHz to 5.35GHz in indoor environments. From the continuous wave measurements at 5.2GHz, the excess path loss, and the statistical characteristics of the temporal and spatial fading were found. By sweeping the frequency over the band, envelope correlation...
