Abstract: As of now, Multi-Carrier modulation (MCM) is considered an effective technique for both wired and wireless communications. Studies have been done by different researchers in this area and analysis of the comparative advantages and disadvantages of the different options for multi-carrier modulation have been extensively done. The place of OFDM, which was once considered as a very strong candidate for multi-carrier modulation technique, has almost been taken over by its successor, WPMCM. This paper reviews the paradigm shift from OFDM to WPMCM as the preferred multi-carrier modulation technique.
