[EN] In this letter, the K-factor is estimated in a typical office scenario based on wideband channel measurements carried out at millimeter-wave (mmWave) frequencies, covering the 25-40 GHz spectrum, in both line-of-sight ...
[EN] This paper presents an analysis of the massive MIMO
channel in an indoor picocell. The analysis is based on the results
of a measurement campaign carried out in the 3.2 to 4 GHz band
in a scenario of reduced size and ...
[EN] Massive multiple-input multiple-output (MIMO) is
considered an enabling technology to achieve large capacities in
multi-user scenarios in the upcoming mobile networks (5G and
beyond). In this paper, the performance ...
[EN] This study presents an analysis of the capabilities of using multi-user multiple input multiple output (MU-MIMO) in indoor environments at the 3-4 GHz band through an empirical characterisation of the MU-MIMO channel, ...

[EN] Propagation channel models based on ray-tracing
techniques can estimate the specular multipath components
(MPCs) reaching the receiver antenna, but have difficulties to
estimate the diffuse components. In this work, ...
[EN] In this paper, a path loss characterization at millimeter-wave (mmWave) frequencies is performed in a typical indoor office environment. Path loss results were derived from propagation channel measurements collected ...
[EN] In this conference contribution, we present
millimeter-wave (mmWave) propagation measurements for an
office environment from 25 to 40 GHz and investigate the
path loss using the most common empirical models proposed
in ...
[EN] Propagation channel models based on ray-tracing
techniques can estimate, with some details, the specular multipath components reaching the receiver antenna, but have
difficulty to estimate diffuse components. In this ...
