Performance Analysis of a 5G Compatible Windowing and Overlapping Scheme Implemented Hybrid Precoded mmWave Massive MIMO NC- OFDM System

Abstract

Non-continuous orthogonal frequency division multiplexing (NC-OFDM) can be considered as a promising technique for obtaining significant sidelobe suppression in baseband OFDM signaling. In this paper, we have conducted an investigative study on the performance analysis of a 5G compatible Windowing and overlapping (WO) scheme implemented mmWave massive MIMO NC-OFDM wireless communication system. In such 32×256 massive MIMO antenna configured Hybrid Precoded and 3D beamforming scheme implemented simulated system, various signal detection (Group detection (GD) approach aided and Cholesky decomposition (CD) based efficient Zero-Forcing (ZF)), modern channel coding (LDPC, and (3, 2) SPC)) and windowing and overlapping for Out-of-band(OOB) power spectral reduction techniques have been implemented with higher order digital modulations (64-QAM, 128- QAM and 256-QAM). On consideration of color image transmission in constructed 3D geometrical mmWave Massive MIMO fading channel, it is observable from MATLAB based simulation study that the (3, 2) SPC) channel encoded simulated system is quite robust and effective in retrieving color image under utilization of Cholesky decomposition (CD) based efficient Zero-Forcing (ZF) signal detection techniques. The impact of tapering of Tukey (tapered cosine) window and various order of digital modulations on system performance in terms of Bit error rate(BER) have also been assessed critically. Additionally, it is noticeable that implementation of 2D image noise filtering technique enhances the quality of retrieved color image.
