Aggregation techniques for energy flexibility
(Universitat Politècnica de Catalunya, 2017-12-04)
Doctoral thesis
Open Access
Covenantee: Aalborg universitetOver the last few years, the cost of energy from renewable resources, such as sunlight and wind, has declined resulting in an increasing use of Renewable Energy Sources (RES). As a result, the energy produced by RES is fed ... -
Design of an impedance source converter for high-performance PV power system applications
(Universitat Politècnica de Catalunya, 2018-07-18)
Bachelor thesis
Open Access
Covenantee: Aalborg universitetThis project describes the principles of impedance-source/quasi-impedancesource inverters, which have the main particularity of being able to operate as voltage-boost inverters. Therefore, the appropriate circuit ... -
Estudi sobre handovers i selecció de cel·les LTE: simulació d'escenaris crítics utilitzant Ray Tracing
(Universitat Politècnica de Catalunya, 2011)
Master thesis (pre-Bologna period)
Open Access
Covenantee: Aalborg universitet[ANGLÈS] In LTE, the handover is a hard handover; the UE is first connected to the source eNodeB, then it gets unattached to the network to connect again to the target eNodeB. This procedure is not fail safe and may cause ... -
Evaluation of pre-filtering techniques for delay-spread compression in Wideband MISO systems
(Universitat Politècnica de Catalunya, 2017-01-08)
Bachelor thesis
Open Access
Covenantee: Aalborg universitetThis thesis describes in quite depth the channel behaviour in wireless communications, pointing some of the complexities that communication systems must face. The document is then focused in Delay Spread Compression (DSC) ... -
LTE-Advanced HetNet Investigations Under Realistic Conditions
(Universitat Politècnica de Catalunya, 2014-07-15)
Master thesis (pre-Bologna period)
Open Access
Covenantee: Aalborg universitet / Nokia Networks[ANGLÈS] With the exponential growth in traffic demands during past years, Heterogeneous Networks (HetNets) are envisioned as the major capacity and performance enhancement enablers by means of increasing the spectral ... -
Medium Efficiency Improvement via Interference Rejection in WiFi Systems
(Universitat Politècnica de Catalunya / Aalborg universitet, 2013-09-10)
Master thesis (pre-Bologna period)
Open Access
Covenantee: Aalborg universitet / Nokia Networks[ANGLÈS] WiFi networks play an integral and essential role in the wireless communications of today's interconnected world. Originally introduced in 1997, the IEEE 802.11 standard has come a long way since its original ... -
