Abstract

Traditional LDPC decoding algorithm such as bit-LLR algorithm has the disadvantage of computational complexity, so the paper studied two simplified algorithms, which were constellation soft decision algorithm based on symbol phases and constellation soft decision algorithm based on symbol distance. These two algorithms calculated each bit soft message by using the phase information and distances of the received symbols. The performance simulation revealed that these algorithms bring a little loss in BER performance, but have a lower computational complexity and can be realized easily.
