摘要

多阈值解码器(MTD)是对自正交码进行译码的最简单的多数解码器。多阈值解码器计算复杂度低，译码硬件实现简单，可用于要求译码速度超过1 Gbit/s的高速通信系统和数据存储系统。考虑了一种利用图形处理器(GPU)现代计算能力的高速软件二进制多阈值解码器。这种MTD的软件实现有助于对从信道接收的几百个完全并行且彼此独立的块进行解码。结果表明，基于GPU GTX 970的软件MTD速度可达350mbit /s。

High Throughput Software Multithreshold Decoder on GPU

Multithreshold decoder (MTD) is the simplest type of majority decoder that decodes self-orthogonal codes. Low computational complexity and simple decoding hardware implementation of multithreshold decoders allow using them in high speed communication systems and data storage systems that require decoding information at speeds above 1 Gbit/s. A high-speed software binary multithreshold decoder using a modern computing power of the graphics processing unit (GPU) is considered. Such software implementation of MTD helps to decode several hundred blocks received from the channel completely parallel and independent from each other. It is shown that the speed of software MTD based on GPU GTX 970 can reach 350 Mbit/s.
