Abstract
Non-contiguous orthogonal frequency division multiplexing (NC-OFDM) has been considered as an outstanding technique for high data rate 5G and beyond 5G wireless communications. In this paper, we have made comprehensive performance evaluative study for a single user NC-OFDM scheme implemented wireless communication system under consideration of millimeter-wave (mmWave) large MIMO antenna configuration. In our 32×256 uniform linear antenna (ULA) configured simulated system under investigation, three selective modern channel coding (LDPC, Repeat and Accumulate and (3, 2) SPC) with a single higher order digital modulation (256-QAM)) and three signal detection (ZF, MMSE and LR-based linear detection) techniques have been utilized. On consideration of color image transmission in AWGN and Rayleigh fading channel, it is observable from MATLAB based simulation study that the Repeat and Accumulate channel encoded simulated system is very much robust and effective in retrieving color image under utilization of MMSE signal detection technique.
Highlights
In perspective of meeting up challenges for developing high spectral and energy efficient 5G radio system, it is noticeable that the present research trend is focusing on new and novel multicarrier transmission techniques using noncontiguous subcarriers such as non-contiguous orthogonal frequency-division multiplexing (NC-OFDM), its enhanced version, Generalized Multicarrier (GMC) multiplexing, or its special case, namely the Non-contiguous Filter-Bank Multi-Carrier (NC-FBMC) technique
The NC-OFDM technique has been proposed in which the Fourier transform is used to provide orthogonally between subcarriers and a cyclic prefix (CP) with temporal length greater than channel delay spread is added to each NC-OFDM symbol to mitigate inter symbol interference
We have presented simulation results for Non-Contiguous Orthogonal Frequency Division Multiplexing Wireless Communication System under consideration of large multiple-input multiple-output (MIMO) antenna configuration and signal transmission with mmWave carrier frequency
Summary
In perspective of meeting up challenges for developing high spectral and energy efficient 5G radio system, it is noticeable that the present research trend is focusing on new and novel multicarrier transmission techniques using noncontiguous subcarriers such as NC-OFDM, its enhanced version, Generalized Multicarrier (GMC) multiplexing, or its special case, namely the Non-contiguous Filter-Bank Multi-Carrier (NC-FBMC) technique. The millimeter-wave (“mm Wave,” for carrier frequencies of 30–300 GHz) communications can be the promising candidate and (iii) high spectrum efficiency: by using a large number of antennas (100 or more), massive multiple-input multiple-output (MIMO) can significantly improve the spectrum efficiency by extensively harnessing the available space resources [6]. In this present study, we have presented simulation results for Non-Contiguous Orthogonal Frequency Division Multiplexing Wireless Communication System under consideration of large MIMO antenna configuration and signal transmission with mmWave carrier frequency
