Abstract :
In order to reduce the Peak-to-Average Power Ratio (PAPR) of multicarrier signals, a DFT precoding technique can be particularly useful. In this paper we propose to combine such a DFT precoding with the OFDM/OQAM modulation to provide a new frequency access scheme, that we call in short DFT-OQAMA. This DFT-OQAMA technique is compared to the Single-Carrier Frequency Division Multiplex Access (SC-FDMA) recently proposed for the UpLink (UL) of the 3GPP LTE system.
