Abstract
A method for spreading a plurality ( M ) of data symbols ( d s ) onto subcarriers ( N ) of a carrier signal for a transmission in a transmission system (400) provides a data vector ( d, ) comprising the plurality ( M ) of data symbols; and generates a spread data vector ( x ) based on the provided data vector ( d ) and a spreading matrix ( D ), with the spread data vector ( x ) comprising a length, which corresponds to the number ( N ) of subcarriers and with the spreading matrix ( D ) being based on a spreading allocation matrix ( 7' ), a base spreading matrix ( C ), and a randomization matrix ( V ).
