Analysis of the Rician K Factor in a Typical Millimeter-Wave Office Scenario

Rubio Arjona, Lorenzo; Rodrigo Peñarrocha, Vicent Miquel; Reig, Juan; Fernandez, H; Pérez, Jesus R.; Torres, Rafael P.; Valle, Luis (Institute of Electrical and Electronics Engineers, 2024-05)

[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 ...
Bivariate Nakagami-m distribution with arbitrary fading parameters

Reig, Juan; Rubio Arjona, Lorenzo; Cardona Marcet, Narciso (Institution of Engineering and Technology (IET), 2002-12-05)

[EN] The bivariate Nakagami-m distribution with arbitrary fading parameters is derived, obtaining the probability density function (PDF), the cumulative density function (CDF) and the central moments. Additionally, limitations ...
Channel Quantization Based on the Statistical Characterization of Spatially Correlated Fading

Domene Oltra, Fernando; Piñero Sipán, María Gemma; Diego Antón, María de; Gonzalez, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 2015-09)

Multiuser multiple-input-multiple-output (MUMIMO) techniques, such as scheduling and precoding, have shown to improve the spectral efficiency of wireless communication systems. However, these techniques require an accurate ...
On Simple Estimators of the alpha-mu Fading Distribution

Reig, Juan; Rubio Arjona, Lorenzo (Institute of Electrical and Electronics Engineers (IEEE), 2011-12)

In this letter, new estimators of the alpha-mu distribution are derived based on the skewness of the logarithmic alpha-mu distribution using the moments method. This distribution has been recently proposed to model the ...
Outage probabilities of dual selection combiners in a correlated Nakagami fading with arbitrary fading parameters

Reig, Juan; Rubio Arjona, Lorenzo; Cardona Marcet, Narciso (IEEE, 2005-02-14)

[EN] In this paper, an infinite convergent series for outage probabilities of dual selection combiners (SC) in a correlated Nakagami fading with arbitrary fading parameters (not necessary identical) is derived. Moments of ...
Performance of Dual Selection Combiners Over Correlated Nakagami-m Fading With Different Fading Parameters

Reig, Juan; Rubio Arjona, Lorenzo; Rodrigo Peñarrocha, Vicent Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2006-09)

This letter presents infinite series expressions for the outage probability, the probability density function (PDF), the average error probability for binary modulations, and average signal-to-noise ratio (SNR) of dual ...
Performance of Maximal Ratio Combiners over Correlated Nakagami-m Fading Channels with Arbitrary Fading Parameters

Reig, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2008-05)

In this letter, performance metrics of maximal ratio combiners (MRC) over correlated Nakagami-m fading are calculated with both arbitrary fading parameters and average powers. We derive the moment generating function ...
The Folded Normal Distribution: A New Model for the Small-Scale Fading in Line-of-Sight (LOS) Condition

Reig, Juan; Rodrigo Peñarrocha, Vicent Miquel; Rubio Arjona, Lorenzo; Martínez-Inglés, María T.; Molina-García-Pardo, José María (Institute of Electrical and Electronics Engineers, 2019-06-06)

[EN] In this paper, a novel form of the folded normal (FN) distribution has been proposed to model the small-scale fading in wireless communications. From a multiple-input multiple-output (MIMO) measurement campaign conducted ...
Time Diversity in Mobile DVB-T2 Systems

Gozálvez Serrano, David; Gómez Barquero, David; Vargas, D.; Cardona Marcet, Narciso (Institute of Electrical and Electronics Engineers (IEEE), 2011-09)

DVB-T2 implements a very flexible time interleaving that allows multiple tradeoffs in terms of time diversity, latency and power saving. In this paper, we study in detail these tradeoffs in the context of mobile reception. ...
