In order to build a high performance low-density parity-check (LDPC) communication link simulation platform, high speed LDPC encoding for information sequence is required. In this paper, a high and flexible throughput LDPC encoding implementation based on a single GPU is proposed. We discuss the parallelism of the LDPC encoding algorithm employs the core parity check bits and single diagonal parity check bits for the fifth generation new ratio. We implement the parallel LDPC encoder on CUDA platform. The experimental results show that our LDPC encoding module achieves a 38-62Gbps throughput for the rate from 1/2 to 8/9 on a single GPU. The results also demonstrate that parallel simulation tasks based on GPUs can achieve a good trade-off between performance and cost.
