This paper proposes a Single-Carrier Frequency-Domain Equalizer(SC-FDE) system based on Turbo channel coding,and performance under the circumstance of the Rayleigh fading channel is analyzed.Moreover,comparisons among different decoding and different iteration times are given for the higher Bits Error Rate(BER) of the traditional SC-FDE system in the complex multipath channel.Simulation results show that the BER of SC-FDE system based on Turbo channel encoding can be reduced five orders of magnitude in comparison with SC-FDE without channel coding system,and BER of the proposed system can be reduced to 10? 7with a 10 dB signal to noise ratio.The reliability of SC-FDE system is enhanced.Hence,it is expected that the system can merge into the future high-speed and high-performance communications.
