Effect of Path Loss Models on Performance of 5G Compatible MIMO WINDOW-OFDM Systems

In wireless communication systems, MIMO (multiple-input and multiple-output) antenna architectures have the capability to enhance channel capacity and reliability. OFDM (Orthogonal frequency division multiplexing) is another proposed technique which is popular for high speed data transmission, robustness to frequency selective channels, low OOB (Out of Band) emission, and low PAPR (Peak to Average Power Ratio). To gain very high data rates for vast number of powerful multimedia and AI capable devices employment of mm-waves frequency bands with the above two technologies is one of the major advancements. But the problems of propagating mm-wave frequency signals are time delay, fading, propagation and scattering losses. So to attain better performance, optimizations of propagation parameters are crucial. This paper shows the effect of Path Loss (PL) models (ABG and CI) to design and analysis of 4×4 MIMO W-OFDM system using several modulation techniques (16-DPSK, 16-PSK, and 16-QAM) for 5G wireless communication. For window filters, Blackman, Hamming, and Bartlett windows have been considered.
