根据消息传递方式的不同,LDPC码的译码算法主要分为两种类型:软判决译码(SDD, Soft Decision Decoding)和硬判决译码(HDD, Hard Decision Decoding)[4]。硬判决译码方式是将信息与判决门限比较并直接进行判决,传递的信息都是0、1这样的二进制信息,比特翻转算法(BF, Bit...

The most suitable decoding algorithm "Layered Belief Propagation Algorithm" is chosen to implement because of lower complex. We will choose Benes Network to solve the problem of routing network because Bense network is better than the traditional routing network. We design the control algorithm of ...

GPU-Accelerated Decoding We implemented a multi-threaded Sum–Product LDPC decoder on a single NVIDIA GeForce GTX 1080 GPU using the NVIDIA CUDA C++ application programming interface. The operations of the Sum–Product algorithm were re-ordered to avoid uncoalesced memory writes and to maximize the...
