  • Method for spreading a plurality of data symbols onto subcarriers of a carrier signal
    Patent number: 9647809
    Abstract: A method for spreading a plurality of data symbols onto subcarriers of a carrier signal for a transmission in a transmission system provides a data vector, including the plurality of data symbols. The provided data vector is transformed, and based on the transformed data vector and a spreading matrix subsequent to the transform, a spread data vector is being created, having a length which corresponds to the number of the subcarriers.

  • Apparatus for amplifying an input-signal
    Patent number: 8803608
    Abstract: Embodiments of the present invention provide an apparatus for amplifying an input-signal. The apparatus includes a switch-mode amplifier for amplifying a digital input-signal. The apparatus is characterized by a generator for generating the digital input-signal based on the input-signal, wherein the generator is configured to generate the digital input-signal such that the digital input-signal is located at a predefined frequency band and such that distortions are located at a frequency higher than the predefined frequency band.
