摘要

本文概述了一种适用于软件定义无线电(SDR)解决方案的低延迟CUDA LDPC解码器实现方法。传统的CUDA LDPC解码器实现方法允许获得非常高的解码器吞吐量，但具有很高的解码延迟。结果表明，提出的CUDA LDPC解码器的实现可以显着降低解码延迟。采用NVIDIA RTX 2080作为仿真平台。得到的时延和吞吐量值满足NGMN规范对超低时延5G业务的技术要求。

Low-Latency CUDA LDPC Decoder for SDR Solutions

This paper outlines a method for low-latency CUDA LDPC decoder implementation applicable for software-defined radio (SDR) solutions. The traditional approach to CUDA LDPC decoder implementation allows to get very high decoder throughput but has high decoding latency. It is shown that the proposed implementation of the CUDA LDPC decoder allows to significantly reduce the decoding latency. NVIDIA RTX 2080 was used as a simulation platform. Obtained latency and throughput values satisfy technical requirements for ultra low latency 5G services in NGMN specifications.
