Theoretical Analysis and Performance Comparison of Multi-carrier Waveforms for 5G Wireless Applications

Fifth generation (5G) wireless technology is a new communication system that must meet different complementary needs: the high data rate for mobile services, low energy consumption and long-range connected objects, latency to ensure real-time critical applications and, spectral efficiency improve overall capacity. The waveforms associated signal processing present real challenge in implementation of each networks. Different research works have discussed this topic; but, these are limited Filter-Bank Multi-Carrier (FBMC), Universal Filtered (UFMC), Orthogonal Frequency-Division Multiplexing (F-OFDM) waveforms. In work, we review technical basics physical layer LTE which uses, OFDM modulation downlink single carrier frequency division multiple access (SC-FDMA) technique uplink. Besides, paper presents diverse candidate 5G systems, including, FBMC, UFMC, F-OFDM, compares techniques with Constant Envelope-OFDM (CE-OFDM), an advantageous form regarding power consumption, especially battery-powered devices. Simulations carried out compare performance OFDM, CE-OFDM, FBMC terms density (PSD) Bit Error Rate (BER). It has been demonstrated (CE-OFDM) constitutes more efficient solution than other technics. By comparison technics, CE-OFDM scheme performances, BER PSD, controllable by values its parameters (M, h, J). This advantage gives designers consider mutual choice between BER. Moreover, (F-OFDM), (FBMC) schemes could constitute density. can be concluded from wave best reducing Peak Average Power Ratio (PAPR) reduce inter-carrier interference (ICI).
