However, forward error correction that takes place at the receiver side has become a real computational challenge. So far, only hardware solutions have offered such high-speed convolutional decoding, which could not be achieved by software solutions. Our paper aims to fill this gap and proposes a software level solution offering such multi-Gbps convolutional decoding. For this intend, we use the massively parallel computing power of NVIDIA GPGPUs and CUDA programming environment to implement a solution. As a decoding method, the Fano algorithm is selected for its relatively low memory requirements and computational complexity. A look-ahead mechanism and compact history in the form of circular queue is presented to support such high throughput. Conducted tests showed that our GPU based algorithm can decode up to 9.25 Gbps.enginfo:eu-repo/semantics/restrictedAccessArticle7512813700038640630001010.1016/j.jnca.2016.08.020Fano algorithmHigh throughput decodingLook-aheadForward error correction (FEC)Compute unified device architecture (CUDA)KEPLERMAXWELL2-s2.0-84985034368
