Mimo Capacity in Uwb Channels in an Office Environment for Different Polarizations

Abstract

Abstract-In this paper, a 4 × 4 indoor Multiple-Input MultipleOutput Ultra-Wideband (MIMO-UWB) measurement campaign in the 2-5 GHz bandwidth is presented. The main contribution of this work is the impact of radio-wave polarization as well as the effect of frequency dependence on the capacity of MIMO-UWB systems working in an office environment. To accomplish this, the capacity for different polarizations is analyzed under two different assumptions: constant or variable Signal-to-Noise Ratio.

Statistical modelling comparison of wearable UWB signal propagation in antithetical corridor environments

“…Published work on non‐wearable UWB investigations in corridors and tunnels includes an exploration of temporal power variations of the UWB radio link in hallways [1], multiple in multiple out antenna capacities for UWB corridor environments [2], and the propagation of UWB signals in underground tunnels [3]. While none of these results are directly applicable to UWB wearable radio links, their methodology is consistent with the current work.…”

Low-Profile and Closely Spaced Four-Element MIMO Antenna for Wireless Body Area Networks

“…The achievable data rate throughput in wireless communication would be multiplied and increased within the multiple-input multiple-output (MIMO) system [6,7]. The MIMO approach helps in optimizing the use of the transmission spectrum and power [8,9]; by exploiting MIMO synthesis, additional paths may be utilized in order to improve the link capacity [10,11].…”
