多种多进制LDPC码译码算法及其硬件实现比较

his paper mainly focuses on the field of non-binary LDPC code decoding algorithm and its hardware implementation, and summarizes the background and research status in this field. We first analyze the research status of the non-binary LDPC code, introduce three classes of decoding algorithm, and analyze their principle, advantage and disadvantage, then the hardware implementation of these algorithms, especially compare them in throughout, resource and performance. Finally, we conclude the advantage and disadvantage of non-binary LDPC code, the fields where it can be used and how could it develop in the future.
