Simulating the error performance of Low-Density Parity-Check (LDPC) codes usually takes a lot of computation time. Inexpensive Graphics Processing Units (GPUs) have recently been used to accelerate the decoding process by allowing the smaller and identical tasks to be performed in a highly parallel manner. In this paper, the authors propose decoding a number of LDPC codes at the same time using GPUs. They show that the decoding speed is improved with their proposed method.
