摘　　要：为了提高汉信码的纠错性能,文中提出了用RS码和Turbo码级联形成RS-Turbo码进行纠错的方法.文中选择RS码作为外码,Turbo码作为内码,二者串行级联形成RS-Tur-bo码.仿真结果表明,在误码率为10-5时RS-Turbo码比RS码有5.85dB的增益,即在相同误码率的情况低信噪比区RS-Turbo码获得了比RS码更好的性能,同时比Turbo码简化了译码难度,RS-Turbo码为汉信码的纠错提供了一种高可靠性低复杂度的方法.In order to improve the error correcting capability of Chinese-sensible code,this paper proposes a method for error correction by eascading RS codes and Turbo codes to form RS-Turbo codes with the RS codes as the outer codes and the Turbo codes as the inner codes.The simulation results show that,when the bit error rate is 10-5,RS-Turbo codes get the gain of 5.85compared with the RS code,namely in the low signal-to-noise ratio region at the same bit error rate,RS-Turbo codes have better performance than RS codes,and also the decoding difficulty of Turbo codes is reduced.RS code is proved to be a method with high reliability and low complexity for error correction of chinese sensible code.
