Abstract

A radio transmission system based on a frequency divisional multiplexing method is described, wherein a transmit symbol comprises a plurality of data symbols assigned to at least two subcarriers. The information of symbols of one time slot is spread across the data symbols of subcarrier of the time slot to produce a transmit symbol being more robust to frequency selective channels.
