A novel approach for spectral efficiency analysis in MIMO cellular networks

George, Geordie; Mungara, Ratheesh K.; Lozano Solsona, Angel; Haenggi, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2017)

The application of stochastic geometry to the analysis of wireless networks is shown to be propelled by (i) a clean separation of time scales, (ii) abstraction of small-scale effects via ergodicity, and (iii) an interference ...
Bit loading for MIMO with statistical channel information at the transmitter and MMSE receivers

Hong, Li; Garcia Armada, Ana; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2012)

Bit and power loading schemes for a single-user multiple-input multiple-output channel using a minimum mean-square error receiver are proposed. Such schemes are derived without the benefit of instantaneous channel state ...
Impact of reflections in enclosed mmWave wearable networks

George, Geordie; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)

We study the impact of signal reflections in enclosed/nwireless networks of wearable devices operating at mmWave/nfrequencies. Given the radical blockage by obstacles and people/n(including the user’s own body) at these ...
Interference surge in full-duplex wireless systems

Mungara, Ratheesh K.; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2015)

Historically unfeasible because of self-interference, full duplexing has now been experimentally demonstrated and is on the verge of commercial feasibility thanks to advances in self-interference cancellation. This will ...
Low-complexity MIMO precoding with discrete signals and statistical CSI

Wu, Yongpeng; Wen, Chao-Kai; Ng, Derrick Wing Kwan; Schober, Robert; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2016)

In this paper, we investigate the design of multiple-input multiple-output single-user precoders for finite-alphabet signals under the premise of statistical channel-state information at the transmitter. Based on an ...
Parallel interference cancellation for Cell-Free C-RANs

Mosayebi, Reza; Mojahedian, Mohammad Mahdi; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)

This paper formulates a linear receiver for the uplink of centralized, possibly cloud-based, radio access networks operating in a cell-free fashion. This receiver, which draws on the notion of soft parallel interference ...
