Abstract :
In this letter, we study four modulation schemes for orthogonal frequency-division multiplexing (OFDM)-based systems. These modulation schemes reduce the sensitivity of OFDM to the residual frequency errors. In particular, the symbol error rates (SER) of these modulations are compared to those of well-known modulations. Furthermore, the impact of the proposed schemes on the OFDM peak to average power ratio (PAPR) is presented.
