  • Publication number: 20200261923
    Abstract: The invention consists of a continuous sorting method and device which highlights the trajectory differences to which fibers of different form factors and particles charged under the joint influence of electrical and gravitational forces could be subjected. Thus, according to the sorting method, the conditions exploit this difference in order to recover/collect the fibers separated from the non-fibrous particles present in the same initial aerosol or to sort fibers exhibiting different form factors.

  • Publication number: 20200259544
    Abstract: A detection method for a MIMO system receiver in which a linear detection is carried out in order to provide an equalised vector. This equalised vector is represented in a reduced basis obtained from the reduction of the channel matrix. It undergoes an iterative noise cancellation process in the representation according to the reduced basis. Upon each iteration, a search is carried out for the component of the equalised vector in the reduced basis located the furthest from an area unperturbed by noise surrounding the product constellation with a tolerance margin, and the point representative of the equalised vector of this area by subtracting therefrom a noise vector in the direction of this component, the module whereof is equal to a fraction of the tolerance margin. The iterative cancellation converges when the equalised vector belongs to the area unperturbed by noise.
