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; and generates a spread data vector based on the provided data vector and a spreading matrix, with the spread data vector including a length, which corresponds to the number of subcarriers and with the spreading matrix being based on a spreading allocation matrix, a base spreading matrix, and a randomization matrix.
