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.
