Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is well recognized as a very efficient multicarrier technology. OFDM has witnessed a significant increase in its utilization within contemporary wideband digital communication systems. The technology possesses several notable benefits, including its capacity to effectively manage challenging channel circumstances, optimize spectrum utilization, mitigate inter symbol interference (ISI), and support high data transmission rates. Hence, it has been employed in several forthcoming wired and wireless communication systems, such as 4G LTE mobile communications. This work primarily concentrates on the performance assessment and investigation of the OFDM system in the presence of Rayleigh fading channels. By analyzing the outcomes of simulations, we may gain insights into various impacts and signal-to-noise ratios (SNRs). In order to determine their respective signal delivery capabilities, channels are compared and ranked. The evaluation of system performance involves assessing the quality of received signals, including factors like as signal quality, bit-error rates (BERs), and peak signal-to-noise ratios (PSNRs).
