    Massive MIMO channel estimation and feedback based on compressed sensing by Pan MAO, Xiaoguang HUANG, Wei WANG, Jian SONG

    Published 2018-12-01
    “…Focused on the issue that the problem of low precision of channel estimation and complex feedback scheme in massive MIMO system,a compression sampling matching pursuit (BCC-CoSAMP) algorithm based on coefficient correlation was proposed in the differential channel estimation and feedback scheme.In this algorithm,the inner product of the relationship between two vectors in the CoSAMP algorithm was replaced by the vector relation based on the correlation coefficient,so the atoms with strong correlation of the original signal were quickly selected to improve the accuracy of channel estimation.The simulation results show that the proposed BCC-CoSAMP algorithm has an improved channel estimation accuracy compared with the CoSAMP algorithm and an average increase of the total system rate of 1.25 bit/(s.Hz) at low signal to noise ratio (SNR).…”

    Alumina and Hafnia ALD Layers for a Niobium-Doped Titanium Oxide Photoanode by Naji Al Dahoudi, Qifeng Zhang, Guozhong Cao

    Published 2012-01-01
    “…They showed a high photocurrent density due to their higher conductivity; however, a low open-circuit voltage was exhibited due to the back-reaction of photogenerated electrons. Atomic layer deposition is a useful technique to form a conformal ultrathin layer of Al2O3 and HfO, which act as an energy barrier to suppress the back electrons from reaching the redox medium. …”

    Le poids de l’instant dans le récit ferroviaire contemporain by Mahigan Lepage

    Published 2015-06-01
    “…Here is the question that arises: how could one make narrative, i.e. duration and continuity (Jean-Paul Goux), from what first appears to be a chaos of atomized instants or snapshots? The analysis of the texts reveals a subtle process of construction in which the instant gradually settles itself into duration, through the course of a prose that runs constantly ahead of thought. …”
