Interference Comparison between OFDM & FH-OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is a common modulation technique that is being used in many of modern wireless communications and standards due to its excellent spectral efficiency and immunity to multipath interference in fading channel. In this paper, a Frequency Hopping Orthogonal Frequency Division Multiplexing (FH-OFDM) system is proposed to enhance the performance of conventional OFDM systems in multiuser interference. Based on simulation results, the Bit Error Rate (BER) performance of the proposed FH-OFDM system is shown to be superior to that of the conventional OFDM system under conditions of multiuser interference and Additive White Gaussian Noise (AWGN) channel.
