提出了一种RS频域编码和LT编码级联的方法,探讨了其在无线数据传输中的应用。分析了RS-LT级联编码相对传统LT码在提高可译码概率方面的优点。该方法在低信噪比情况下的大数据量信息传输应用中具有很好的性能。仿真结果表明,在低信噪比的环境下可以有效恢复传输信息,提高接收图像品质。

A method of combining RS frequency coding and LT coding concatenated for wireless data transmitter - receiver is presented in this paper. Its superiority to the traditional LT code in decoding probability is analyzed as well. The proposed method features well in performance in the application of mass data transmission in low signal - to -noise ration environment. The results of simulation indicate that this method can recover the transmitted information efficiently and improve the quality of the received image even under the condition of low signal - to - noise ratio.
