Abstract

OFDM system operates at high speed data rate over selective fading channel. In this paper a Turbo Coded OFDM (COFDM) system was presented and simulated over Rayleigh selective fading mobile radio channel. The type of the turbo code used is a parallel concatenated conVolutional code (PCCC). The simulation results include a comparison between coded and uncoded OFDM system with different number of subcarrier. Furthermore, the number of iterations and input frame lengths effects on the performance were investigated. The result shows that the performance of OFDM system is enhanced when using turbo code in the OFDM system. Furthermore, the performance enhancement is increased as the number of iterations and input frame length is increased.
