  • Method for channel estimation
    Patent number: 8824534
    Abstract: The invention relates to a method of estimating BEM coefficients of the Channel taps of a transmission Channel of an OFDM System having a given pilot arrangement, comprising, at the receiver side of the transmission Channel, the Steps of a) subsampling a received OFDM symbol in the frequency domain into a set of subsequences, b) inverse Fourier transforming each subsequence into a transformed subsequence, and c) estimating Fourier coefficients of a truncated Fourier series expansion model of the Channel taps from the set of transformed subsequences.
    Type: Grant

    Date of Patent: September 2, 2014
    Assignees: Universitat Wien, Technische Universitat Wien
    Inventors: Tomasz Hrycak, Saptarshi Das, Hans Georg Feichtinger, Gerald Matz
  • Method for channel equalization
    Patent number: 8755429
    Abstract: A method of equalizing a signal received over transmission channel defined by BEM coefficients of a basis expansion model of its channel taps, comprising the step of approximately solving the relation (I) for x[n] by an iterative method, n being the index of time, y[n] being the received signal, x[n] being the equalized signal, Bm[n] being the mth basis function of the basis expansion model, M being the model order of the basis expansion model, and blm being the BEM coefficient of the mth of the basis function of the lth channel tap, and w[n] being optional noise.
