Channel Estimation in Spatially Correlated High Mobility MIMO-OFDM Systems

MIMO-OFDM is a transmission method very sensitive to the channel time-variations arising in high mobility scenarios due to the appearance of inter-carrier interference (ICI). In this paper we propose an algorithm for channel estimation in MIMO-OFDM systems that uses a Basis Expansion Model that exploits temporal, frequency and spatial correlations within the wireless channel in high mobility sc...

Giant enhancement in vertical conductivity of stacked CVD graphene sheets by self-assembled molecular layers.

Layer-by-layer-stacked chemical vapour deposition (CVD) graphene films find applications as transparent and conductive electrodes in solar cells, organic light-emitting diodes and touch panels. Common to lamellar-type systems with anisotropic electron delocalization, the plane-to-plane (vertical) conductivity in such systems is several orders lower than its in-plane conductivity. The poor elect...

Corrigendum: Correlation of p-doping in CVD Graphene with Substrate Surface Charges

Correlations between the level of p-doping exhibited in large area chemical vapour deposition (CVD) graphene field effect transistor structures (gFETs) and residual charges created by a variety of surface treatments to the silicon dioxide (SiO2) substrates prior to CVD graphene transfer are measured. Beginning with graphene on untreated thermal oxidised silicon, a minimum conductivity (σ(min)) ...

High-mobility graphene on liquid p-block elements by ultra-low-loss CVD growth

The high-quality and low-cost of the graphene preparation method decide whether graphene is put into the applications finally. Enormous efforts have been devoted to understand and optimize the CVD process of graphene over various d-block transition metals (e.g. Cu, Ni and Pt). Here we report the growth of uniform high-quality single-layer, single-crystalline graphene flakes and their continuous...
