Research led by Prof. José A. Lázaro

Current research has been focused on:

- Architecting a knowLedge-defined 5G-enabLed network Infrastructure towArd the upcomiNg digital soCiEty-B. ALLIANCE-B (2018-2020)

where we are developing infraestruture for 5G networks.

In line with the objectives of the project: Architecting a knowLedge-defined 5G-enabLed network Infrastructure towArd the upcomiNg digital soCiEty-B. (ALLIANCE-B), we are developing 5G infrastructures for demo purposes

We follow integration of WDM-PON and 5G hauling as proposed in 5G-PPP projects as 5G-Xhaul (www.5g‐xhaul‐project.eu/), for provisioning optical fronthauling between the RRH (Remote Radio Head) at the antenna tower and the BBU (BaseBand Unit) at the CO (Central Office), see Figure at [Link to OFC 2017 Zou et al.]

Specifically, our Scenario for capacity enhancement of and flexible resource provisioning in 5G mobile networks (Fig 1), can be implementing by e.g. by combining non-orthogonal multiple access (NOMA) and multiband carrierless amplitude phase modulation (multiCAP) [Link to IEEE JLT 2017 Altabas et al.]

Fig 1

We implement analog RoF fronthaul, as describe in [Link to IEEE Commun. Mag. 2014 Rost et al.] and [Link to IEEE JLT 2013 Liu et al.], including (Fig 2): a) Terminal implementing: FBMC, UFMC, GFDM, OFDM, NOMA-CAP; b) RRH receiving FBMC, UFMC, GFDM, OFDM, NOMA-CAP; c) 10 to 25 km transmission of SSMF by direct modulated laser; d) C-RAN at CO
