Evaluation of 5G Modulation Candidates WCP-COQAM, GFDM-OQAM, and FBMC-OQAM in Low-Band Highly Dispersive Wireless Channels
(Hindawi, 2017)We analyse some of the candidates for modulations for 5G: FBMC-OQAM, GFDM-OQAM, and WCP-COQAM. Unlike most of the related bibliographies, which are oriented to mobile communications, our research is focused on 5G in cognitive ... -
Evolution of residual stresses induced by machining in a Nickel based alloy under static loading at room temperature
(Elsevier, 2014)Tensile residual stresses are very often generated on the surface when machining nickel alloys. In order to determine their influence on the final mechanical behaviour of the component residual stress stability should be ... -
Experimental analysis of cutting force reduction during ultrasonic assisted turning of Ti6Al4V
(Elsevier Ltd., 2019)The machining of difficult-to-cut materials involves limitations leading to low productivity in conventional machining processes due to high cutting forces and tool wear rates. The ultrasonic ... -
Experimental and FEM analysis of surface integrity when broaching Ti64
(Elsevier, 2018)The performance of aeronautic critical components is strongly dependent on its fatigue behavior, which is directly linked to their surface integrity condition. Broaching operation is a machining operation extensively used ... -
Experimental and Numerical Simulation Investigation on Deep Drawing Process of Inconel 718 with and without Intermediate Annealing Thermal Treatments
(MDPI AG, 2020)The aeronautical industry is moving from high-capacity large-airplane construction to low-capacity small-airplane construction. With the change in the production volume, there is a need for more e cient manufacturing ... -
Experimental uncertainty decompositions of aerodynamic coefficients affected by operative condition variations
(Elsevier Ltd., 2020)A twofold analysis is performed on an experimental set-up comprising a low-Reynolds wind tunnel, with the aim of quantifying the effect of measurand uncertainties and operative condition variations in the lift and drag ... -
Factor graph based detection approach for high-mobility OFDM systems with large FFT modes
(Springer, 2012)In this article, a novel detector design is proposed for orthogonal frequency division multiplexing (OFDM) systems over frequency selective and time varying channels. Namely, we focus on systems with large OFDM symbol ... -
