摘　　要：分析了单载波频域均衡技术和Turbo编译码技术,研究了基于这两种技术的无线图像传输方案,并对联合SC-FDE和Turbo码图像传输方案进行了数值仿真研究。仿真结果表明,把SC-FDE技术和Turbo码技术结合应用到无线图像传输中可以明显提高接收图像质量,改善信噪比性能。相比较传统无SC-FDE的图像传输方案,在误码率为10-5时有约1.5dB的增益。从而表明,联合SC-FDE和Turbo码可以实现图像的更加可靠的传输,是实现图像的高速传输和高频谱利用率的有效方法。In this paper,the application of SC-FDE（single-carrier frequency domain equalization） and Turbo codes in image transmission is studied.And the image transmission system based on SC-FDE and Turbo codes is discussed and simulated.The simulation results show that more reliable transmission could be realized by combination and application of SC-FDE and Turbo codes in the image transmission of wireless channel system,and about 1.5 dB gain for a target BER of 10-5 in terms of SNR（signal to noise ratio） could be achieved.This also proves that the combination of SC-FDE and Turbo codes could realize the reliable image transmission and is an effective way for realizing high-speed image transmission and high-utility rate of frequency spectrum.
