Belief propagation( BP) algorithm can generate soft information for systematic polar codes( SPC)to make decoding decisions and the soft information also can be used as extrinsic information in turbo decoding.This paper first provides a detailed description of BP algorithm based on the structure of channel polarization.Then,it introduces two decision methods,one of which is by exploiting the soft information while the other one is by using polar encoding.The decoding performance under these two methods are c...
