| Abstract: | In this paper the application of orthogonal frequency division multiplexing （OFDM） and Turbo codes in image transmission is studied. And the effect of Turbo codes image transmission system improved by OFDM is discussed and simulated. The simulation results show that a combination and application of OFDM and Turbo codes in the image transmission of wireless channel system can realize more reliable transmission. Consequently, OFDM is an effective way for improving Turbo codes, realizing high speed image transmission and high utility rate of frequency spectrum. |
