Stochastic turbo decoder is a new scheme for turbo codes. But the long decoding latency and high complexity are two main challenges for fully parallel stochastic turbo decoders. In this paper, we proposed a novel stochastic turbo decoder scheme with two high accuracy stochastic operator modules, including no-scaling stochastic addition and stochastic normalization operator, which can improve the decoding...
It is very important for the future wireless or mobile communication systems to achieve high speed Turbo decoder. A novel Turbo decoder structure and implementation scheme are proposed in this paper. The MAX-log-MAP algorithm is implemented in probability domain with stochastic computation method in this paper. The signed stochastic calculations are adopted to meet the requirements of log-MAP decoder...
