Heat treatment of commercial polydimethylsiloxane PDMS precursors: Part II. Thermal properties of carbon-based ceramic nanocomposites

Srisaran Venkatachalam, Stéphane Lenfant, Michael Depriester, Abdelhak Hadj Sahraoui, D. Hourlier

Organosilicon polymer-derived ceramic (PDC) materials have been extensively studied for their various properties such as mechanical, chemical and electrical properties. One of the least explored properties of PDC is their thermal properties, required for designing a heat energy converter. In this...

Channel correlation-based approach for feedback overhead reduction in massive MIMO

Frédéric Challita, Pierre Laly, Marwan Yusuf, Emmeric Tanghe, Wout Joseph, Pierre Degauque, M. Lienard, Davy Gaillot

For frequency-division duplex multiple-input-multiple-output (MIMO) systems, the channel state information at the transmitter is usually obtained by sending pilots or reference signals from all elements of the antenna array. The channel is then estimated by the receiver and communicated back to the...

Iuliacumite: A Novel Chemical Short-Range Order in a Two-Dimensional Wurtzite Single Monolayer InAs 1– x Sb x Shell on InAs Nanowires

M. Schnedler, T. Xu, Isabelle Lefebvre, J.-P. Nys, S R Plissard, Maxime Berthe, H. Eisele, R. E Dunin-Borkowski, Ph. Ebert, B. Grandidier

A chemical short range order is found in single monolayer InAs 1-x Sb x shells, which inherit a wurtzite structure from the underlying InAs nanowire, instead of crystallizing in the energetically preferred zincblende structure. The chemical order is characterized by an anti-correlation ordering...

Optical external efficiency of terahertz quantum cascade laser based on Čerenkov difference frequency generation

A. Hamadou, Jean-Luc Thobel, S. Lamari

In this paper, we consider terahertz sources based on Čerenkov difference frequency generation in a dual-wavelength mid-infrared quantum cascade laser and calculate analytically the optical external efficiency of the out-going terahertz wave. The mid-infrared pumps operate simultaneously and have a...

Serial Concatenation of Binary LDPC Codes with Iterative Decoding

Latifa Mostari, Abdelmalik Taleb-Ahmed

In this paper, a binary serial turbo LDPC code is presented. It represents a serial concatenated LDPC codes separated by interleavers, with iterative decoding. In this work, we aim to investigate the performance evaluation of concatenated code, with reduced complexity and decoding delay, associated...

Hybrid virtual polarimetric massive MIMO measurements at 1.35 GHz

Frédéric Challita, Pierre Laly, M. Lienard, Emmeric Tanghe, Wout Joseph, Davy Gaillot

The polarimetric massive multiple‐input multiple‐output (MIMO) radio channel of an indoor line‐of‐sight scenario is investigated at 1.35 GHz using a real‐time radio channel sounder. The 8 × 12 massive MIMO transmitter is constructed using a hybrid architecture including a vertical uniform linear...
