Abstract

The present invention concerns a method and a device for forming a DFT-spread OFDM symbol comprising data and pilots. The present invention: - forms a pilot symbol in the time domain, the pilot symbol comprising at least two parts, a first part of the pilot symbol comprising samples of front pilots, a second part of the pilot symbol comprising null values, - performing a DFT-spread OFDM modulation of the pilot symbol, - precoding the data, - putting the precoded data under the form of a data symbol in the time domain, the data symbol comprising at least two parts, a first part of the data symbol comprising null values, a second part of the data symbol comprising the data, - performing a DFT-spread OFDM modulation of the data symbol, - modifying a part of the DFT-spread OFDM modulated data symbol, - combining the modified DFT-spread OFDM modulated data to the DFT-spread OFDM modulated pilot symbol.
