Different from the presented work, where an optimal interleaver is considered mostly for reducing the correlation between parity bits of different paths and bit error rate(BER) of iterative decoding, the method based on prime sequences is demonstrated in this paper to obtain a family of interleavers inde.

Query processing based on prime sequence labeling

And then using Fano algorisms,it implements the softdecision sequential decoding of systematic convolutional code and analyzes the properties,which play a good foundation for the future engineering application.

A new sequential decoding method based on Genetic algorithm is proposed.
