摘　　要：根据在3种不同内码情况下(ST Turbo TC,STTC,卷积码),LT code在慢瑞利衰弱信道中的性能比较,讨论不同内码对LT code性能的影响,说明ST Turbo TC与LTcode相结合后的优越性能。This paper first analyzes the theory of LT code and discusses it's performance under rayleigh fading channel.At last,it discusses the performance of LT code with three different inner code(ST Turbo TC,STTC,convolutional codes),which shows the significant influence of inner code and the good performance of ST Turbo TC combining with LT code.
