Abstract :
It is necessary for the decoder of turbo code to know the SNR of some channel, otherwise there is loss of SNR. A new algorithm is put forward on the basis of the high order statistic analysis, and it is simpler and more effective than the algorithm in Summers et al. (1998), what is more, it is not only applied to AWGN channel, but also applicable to Rayleigh channel, which is proved by the sensitivity simulation of SNR estimation to decoding quality of turbo code.
