Simulating of OFDM Systems for Noise Abolition in the Long-Term Evolution application

Abstract

Communication systems are basic in the modern world. OFDM has been used for noise abolition in LTE generation. In this paper, a simulation of OFDM system has been used by MATLAB GUI. Four cases have been studied, simulated, and analyzed. According to the type of noise in the channel, we used these parameters as an effect on the system. The effect of three parameters has been used for each case. The parameters include the number of the subcarrier in OFDM system, the number of samples on each subcarrier and the signal to noise ratio. The simulation used in this paper according to the mathematical communication equations gives accurate and fast results.
