| Abstract | Orthogonal Frequency Division Multiplexing (OFDM) is a very efficient multicarrier technique. OFDM is used more and more in recent wideband digital communications. It has numerous advantages such as the ability to handle severe channel conditions, efficient spectral usage, reduced inter symbol interference (ISI), and high data rate. Therefore, it has been utilized in many future wired and wireless communication systems 4G LTE mobile communications. In this paper, mainly focus on the performance evaluation and study of OFDM system over multipath fading channels such as AWGN, Rician and Rayleigh fading channels. Based on simulation results will make us understand some of these effects and signal-to-noise ratios (SNRs), channels are compared together in order to rank them according to the delivered signal. Quality of the signals, bit-error rates (BERs), and peak signal-to-noise ratios (PSNRs) of the received signals are the aspects in which system performance is evaluated. |
