Performance Analysis of OFDM, FBMC and UFMC Modulation Schemes for 5G Mobile Communication MIMO systems

Abstract

The rapid development in the field of Internet and mobile communication systems has demanded the technology of the 5th generation communication mimo systems to develop rapidly over the past few years. The name given to the next generation of wireless communication is 5G. Till now 4G provided the speed upto few mbps but the main drawback lies in reproducing the real time applications. In this scenario, 5th generation systems come into picture. 5g modulation schemes are developed exclusively for the Internet, video, voice, and data services. The ODFM has few disadvantages high peak power to average power ratio resulting in requirement of the high-power amplifiers. So, to overcome this problem, 5g modulation schemes Filter bank multi carrier systems and universal filter multicarrier systems are used. As we go higher the frequency range, there is an issue of frequency selectivity and thus by using the mimo techniques the problem of frequency selectivity can be solved. In this paper, we have compared the performance analysis of the Orthogonal frequency division multiplexing (OFDM) mimo system, Filter bank multicarrier (FBMC) mimo systems and Universal filter multicarrier (UFMC) mimo systems with respect to Bit error rate, power spectral density, data rate and issue of spectral confinement which is observed in FBMC and UFMC is resolved and thus reducing the complexity of the 5g system.
