Abstract
This paper presents a multi-user channel measurement campaign using a recently developed VNA-based multi-link channel sounder in an indoor hall scenario. The channel sounder architecture and comparison with the conventional multi-link channel sounder are firstly demonstrated, with a focus on the cost-effectiveness of the developed channel sounder. The two multi-user location combinations are considered in these channel measurements. The empirical channel data for the multi-user is then processed using the calibration procedure. By using the classical beamforming algorithm, the power-angle-delay-profiles (PADPs) are obtained from the calibrated channel response. The channel characteristics of the two links, i.e., PADP, delay and angular spread, are analyzed and compared.
