Performance Analysis of OFDM, W-OFDM and F-OFDM Under Rayleigh Fading Channel for 5G Wireless Communication

The OFDM multiple carrier modulations are more secure and suitable for a special fading that is known as a frequency selective fading. To minimize the queue in the 5G waveform, it is likewise much important to resize the bandwidth in the OFDM based technology. Consequently, Filtered Orthogonal Frequency Division Multiplexing also known as a spectrally localized waveform technology which is the primary approach. Windowed-OFDM (W-OFDM), where each symbol is categorized by windowed and every symbol is overlapped in the special time domain that is known as the classical OFDM scheme. The traffic scenario is processed by the individual sub-bands. This article presents the comparison of the performance analysis of OFDM, W-OFDM, and F-OFDM systems using BPSK, QAM, 16-PSK, 8-QAM, QPSK, and 16-QAM modulation techniques under Rayleigh fading channel. The main aim of this article is to focus on examining the effective performance of OFDM, W-OFDM, and F-OFDM in terms of PSD, Bit error rate, and signal to noise ratio. The simulated values are analyzed in terms of PSD and BER.
