Waveforms for the Massive MIMO Downlink: Amplifier Efficiency, Distortion and Performance
, 2015 In massive MIMO, most precoders result in downlink signals that suffer from high PAR, independently of modulation order and whether single-carrier or OFDM transmission is used. The high PAR lowers the power efficiency of the base station amplifiers.

PAR-Aware Large-Scale Multi-User MIMO-OFDM Downlink [PDF]
, 2012 We investigate an orthogonal frequency-division multiplexing (OFDM)-based downlink transmission scheme for large-scale multi-user (MU) multiple-input multiple-output (MIMO) wireless systems.

, 2014 O ensino da Engenharia tem vindo gradualmente a evoluir da exclusiva e sempre necessária qualificação técnica para uma qualificação mais abrangente e mais atenta à diversidade dos estudantes. Para fazer face a esse desígnio não só se reorganizaram os currículos da formação dos engenheiros de forma a privilegiar as chamadas soft skills como tem vindo a ...

Decolonising knowledge: Enacting the civic role of the university in a community-based project
South African Journal of Education, 2018 The need to work in partnership with communities in a meaningful and impactful way has become a core part of university planning in many countries around the world. In the Global South, the potential for the Eurocentric knowledges and power structures to

Let there be light : light interception method update for oil palm (Elaeis guineensis Jacq.) canopies [PDF]
, 2018 Light interception (photosynthetically active radiation, PAR) experiments in oil palm (Elaeis guineensis Jacq.) plantations are scarce and often performed decennia ago, in Southeast Asia and without a clear methodology.

On the Structure of ${\rm ZnI_2}$
, 2006 A new structure for ${\rm ZnI_2}$ is proposed which it exists in tetragonal state. In this structure the ${\rm ZnI_2}$ molecule exists in a nonlinear array and forms the basis of the tetragonal unit cell with one basis per unit cell.

La source de ‘l’approximation’ dans par ici, par là, par là-bas [PDF]
Linx, 2005 Les expressions du type par ici, par la, par la-bas sont considerees comme plus ou moins figees. Avec ces expressions, le regime de par est interprete, en general, comme un lieu dont la frontiere est floue. A travers des analyses syntaxico-semantiques, nous demontrerons que l’approximation portee sur la representation du regime de par est le resultat ...
