Abstract

Multicarrier modulation (MCM) attracts a lot of attention for high-performance wireless transmissions. Nowadays, orthogonal frequency division multiplexing (OFDM) with the cyclic prefix (CP) insertion is the most widespread modulation among all MCM and this thanks to its simplicity and its robustness against multipath fading using the CP. Nevertheless, the CP-OFDM technique causes a loss of spectral efficiency due to the CP as it contains redundant information. Moreover, the rectangular prototype filter used in CP-OFDM has a poor frequency localization. This poor frequency localization makes it difficult to respect the stringent specifications of future wireless systems.
