Abstract:
Wireless networks and mobile communication have developed into essential instruments
in our daily lives. It is the technology sector in the communication industry that is
expanding and thriving the fastest. To better and safely handle all of the requirements of
fifth-generation wireless networks, appropriate and optimal modulation schemes are used
in conjunction with the fastest-expanding wireless network technology.
Despite its well-known advantages, OFDM has a few shortcomings that make it
insufficient to handle the scenarios envisaged for 5G wireless networks. To address the
drawbacks of OFDM, several waveforms have been proposed for 5G wireless networks
thus far. To analyze the performance of 5G waveform schemes based on SE, PAPR, PSD,
and BER for a few selected waveforms, this thesis uses the MATLAB software tool.
Additionally, it explains how each waveform scheme can be enhanced by employing its
characteristics and offers suggestions for how to use each waveform successfully.
According to the simulation results, UFMC has a higher SE than FBMC and F-OFDM up
to burst durations of 60ms. However, FBMC has a larger SE than UFMC and F-OFDM
over burst durations of 60ms. UFMC has a lower PAPR value than FBMC and F-OFDM,
according to PAPR. It uses less battery power than the others, in other words. The side
lobes of UFMC are more comparable to the normalized frequency in terms of the PSD than
FBMC and F-OFDM. When it comes to BER, FBMC has a lower BER value than UFMC
and F-OFDM.
The outcomes of the simulation demonstrate that FBMC may be effectively used for
sending lengthy bursts per frame. Contrarily, UFMC is utilized to send brief bursts per
frame. Additionally, employing 256QAM for UFMC with 1024 FFT, 64QAM for FBMC
with 512 FFT, and 1024QAM for F-OFDM with 512 FFT can reduce the amount of energy
use. Using UFMC with a high number of FFT, FBMC with a high number of symbols, and
F-OFDM with a high filter length, according to interference, will be enough to reduce it.
By using FBMC with a minimal number of FFT, UFMC with minimal guard bands, and
F-OFDM with an increasing overlapping factor, the quantity of BER can be reduced.
