A Novel Modulation Technique for 5G Mobile Communication System

By the year 2020, the data traffic can be approximately increase by 30%, which cannot support by existing mobile technologies. Hence, there is a requirement of next generation wireless communication (5G) which aim to provide a high capacity, data-rate at the speed of 1Tbps. By selecting a better modulation technology, the required capacity and data-rate can be achieved. In this study we design aprototype filter for multicarrier modulation candidates of 64-subchannels for 5G mobile communication system: Orthogonal Frequency Division Multiplexing (OFDM) often used in 4G mobile and Filter Band Multi-Carrier (FBMC) a promising candidate for 5G mobile communication system. We judge the magnitude response of prototype filter for OFDM and FBMC. Magnitude response for overlapping factor (K = 2, 3, 4) is also evaluated. Finally the constellation plot clearly defines the transmission scheme of FBMC and OFDM. FBMC proof to be preeminent method and outperforms OFDM due to the fact that FBMC do not use (CP) cyclic prefix and wide guard band un-like OFDM.
