Monte-carlo performance analysis of OFDM system in the presence of multi-path fading environment and non-Gaussian noise

Abstract

In recent years, the fantastic growth of using mobile devices and wireless communication tools leads to requirements of higher data rate for the connection and higher capacity for the subscribers in the communication industrial area. Therefore, multi-carrier transmission technique has been proposed to be a robust and efficient technique to transmit data over severe communication channels. The Orthogonal Frequency Division Multiplexing (OFDM) is a very efficient multi-carrier technique that can fulfill high demands of users. This technique has been studied by many researchers, mainly as mean to combat fading and Additive White Gaussian Noise (AWGN). However, in the real communication environment, the main source of additive noise is man-made noise which by its nature is impulsive. Impulsive noise is composed by thermal noises in electronic devices of receivers and incoming electromagnetic impulses from nearby other electrical devices. These kinds of noise inject high electromagnetic energy into receivers so that it strongly affects to quality of received signals. Therefore, in this paper, the performance of OFDM system in the presence of multi-path fading environment and non-Gaussian noise, which modeled by the class A Middleton noise, is illustrated by using the Monte Carlo simulation technique.
