Design and Implementation of Advanced Modulation Technique in 5G Communications System

Abstract

The orthogonal frequency division multiplexing (OFDM) modulation is the most popular multicarrier modulation scheme nowadays to support fourth-generation wireless communication (4G). However, due to the rectangular pulse shaping and use of cyclic prefix (CP), The OFDM systems exhibit very high-frequency leakage and poor stopband attenuation. In the light of these limitations, Fifth Generation (5G) Mobile broadband radio access is the promising technology that will develop to satisfy the demand of continuous increasing data traffic. It also allows subscribers and machines to exchange big data traffic rates, Gigabit, with virtually small latency. Actually, the development of new wireless technology generation in the fifth generation usually has a new modulation scheme in the physical layer.
