IMPLEMENTING UNIQUE WORD OFDM IN MIMO FILTER-BANK MULTICARRIER SYSTEMS

This paper presents a proposed work aimed at addressing the frequency selectivity of channels using Orthogonal Frequency Division Multiplexing (OFDM) and achieving high spectral efficiency through the implementation of the Filter Bank (FB) technique. The absence of a cyclic prefix in FBMC (Filter Bank Multi-Carrier) contributes to increased bandwidth efficiency. Additionally, this study introduces self equalization as a property of FBMC in massive Multiple-Input Multiple-Output (MIMO) systems, which has several beneficial effects. These effects include peak-to average power ratio (PAPR), reducing complexity, system latency, sensitivity to carrier frequency offset (CFO), and increasing bandwidth efficiency. The proposed work focuses on investigating three key parameters: pilot contamination effect, self equalization, and CFO analysis. By analysing these parameters, the study aims to provide insights into optimizing system performance and enhancing overall efficiency. The simulation of the proposed work is conducted using MATLAB R2013a, which allows for accurate modeling and evaluation of the system under various scenarios. The results of this proposed work are expected to contribute to advancements in wireless communication systems by mitigating the frequency-selectivity of channels, improving spectral efficiency, and optimizing system parameters for enhanced performance.
