Abstract

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, we propose decoding a number of LDPC codes at the same time using GPUs. We show that the decoding speed is improved with our proposed method.
